, for example , a door trim for an automobile . the interior component 1 has an outer surface exhibiting a design property , and an inner surface on the other side of the outer surface . at the four corners of the inner surface , there are formed first to fourth clip mounting seats 2 ( 2 a to 2 d ) to each of which a clip 3 is attached . the clip 3 has upper and lower flange portions 34 a and 34 b between which the clip mounting seat 2 is held . as shown in fig3 and 4 , a first clip mounting seat 2 a has a first attachment hole 24 a exhibiting an inner diameter slightly larger than the outer diameter of a neck portion 34 c of the clip 3 . the first attachment hole 24 a serves as a reference hole for setting the position of the door trim 1 with respect to a vehicle body panel p . the first attachment hole 24 a is set to be of such a size that it cannot absorb a mounting error in the vertical direction and / or the front - rear direction of the door trim 1 with respect to the vehicle body panel p . as shown in fig1 , a second clip mounting seat 2 b has a second attachment hole 24 b . the second attachment hole 24 b is a longitudinally ( vertically ) elongated hole capable of absorbing the mounting error in the vertical direction of the door trim 1 with respect to the vehicle body panel p . as shown in fig1 , a third clip mounting seat 2 c has a third attachment hole 24 c . the third attachment hole 24 c is a laterally elongated hole capable of absorbing the mounting error in the front - rear direction of the door trim 1 with respect to the vehicle body panel p . as shown in fig1 , a fourth clip mounting seat 2 d has a fourth attachment hole 24 d . the fourth attachment hole 24 d has a large diameter allowing absorption of the mounting error in the vertical direction and the front - rear direction of the door trim 1 with respect to the vehicle body panel p . the first to fourth clip mounting seats 2 a to 2 d have the attachment holes 24 a to 24 d which are different from each other . with the exception of the attachment holes 24 a to 24 d , the first to fourth mounting seats 2 a to 2 d are of the same construction . as shown in fig3 to 7 , the first clip mounting seat 2 a is formed integrally with the interior component 1 . the first clip mounting seat 2 a is formed of a synthetic resin exhibiting rigidity . the first clip mounting seat 2 a has a peripheral wall 20 and a clip attachment surface 22 . the peripheral wall 20 protrudes from the interior component 1 . the clip attachment surface 22 is formed so as to close the upper side of the peripheral wall 20 . as shown in fig3 , the first clip mounting seat 2 a has an opening 20 a for opening a part of the peripheral wall 20 . the clip attachment surface 22 is provided with a guide groove 26 and a pair of tongues 28 . the neck portion 34 c of the clip 1 is inserted into the clip attachment surface 22 from the opening 20 a , and is guided to the first attachment hole 24 a by the guide groove 26 . the tongues 28 protrude from both edges 26 a of the guide groove 26 toward the first attachment hole 24 a . each tongue 28 has a distal end 28 a and a protrusion 28 b . the distal end 28 a has an arcuate recess . the distal end 28 a is situated on the same arc line of the inner peripheral surface of the first attachment hole 24 a . the distal end 28 a is an arc of substantially the same radius as the first attachment hole 24 a . the protrusions 28 b protrude into the guide groove 26 so as to reduce the groove width of the guide groove 26 . the distance between the two protrusions 28 b is smaller than the outer diameter of the neck portion 34 c of the clip 3 . as shown in fig9 to 11 , the pair of tongues 28 are deflected , and the neck portion 34 c of the clip 3 passes between the pair of tongues 28 to reach the bottom of the first attachment hole 24 a . the pair of tongues 28 are restored from deformation , and the distance between the two protrusions 28 b becomes smaller than the outer diameter of the neck portion 34 c of the clip 3 . as shown in fig3 , the clip 3 is a single member formed of a synthetic resin exhibiting rigidity . the clip 3 integrally has a base plate body 30 , an anchor body 32 and an attachment body 34 . the base plate body 30 is of a disc - like configuration , and constitutes the base of the clip 3 . the anchor body 32 protrudes from the upper surface of the base plate body 30 . the attachment body 34 protrudes from the lower surface of the base plate body 30 . a stabilizer 30 a is formed in the outer periphery of the base plate body 30 . the stabilizer 30 a is formed as a disc upwardly extending from the entire periphery of the base plate body 30 . the anchor body 32 is inserted into a mounting hole ( not shown ) of the vehicle body panel . on the outer periphery of the anchor body 32 , there are formed a plurality of ( e . g ., four ) elastic claws 32 a . the anchor body ( swollen body ) 32 is reduced in diameter when it is inserted into the mounting hole of the vehicle body panel , and it is increased in diameter when reaching beyond the mounting hole . the anchor body 32 is engaged with the mounting hole of the vehicle body panel . as a result , the door trim 1 is mounted to the vehicle body panel . the attachment body 34 has flange portions ( an upper flange portion 34 a and a lower flange portion 34 b ) and the neck portion . the upper flange portion 34 a and the lower flange portion 34 b hold the clip attachment surface 22 of the first clip mounting seat 2 a therebetween . the neck portion 34 c is of a small diameter and connects the upper and lower flange portions 34 a and 34 b to each other . for attaching the clip 3 to the first clip mounting seat 2 a , the anchor body 32 of the clip 3 is first gripped with fingers . the neck portion 34 c is inserted into the guide groove 26 while causing the clip attachment surface 22 to be situated between the flange portions 34 a and 34 b . as shown in fig9 and 10 , the neck portion 34 c pushes the protrusions 28 b of the pair of tongues 28 . the pair of tongues 28 are deflected so as to move away from each other . the pair of tongues 28 contact both edges 26 a of the guide groove 26 ( abutment state ). in the abutment state , the distance between the two protrusions 28 b is smaller than the outer diameter of the neck portion 34 c of the clip 3 . a distance s is generated between the tangent extending from the neck portion 34 c and the distal end line extending from the distal end of each protrusion 28 b . in the abutment state , the neck portion 34 c is further pushed toward the attachment hole 24 . the neck portion 34 c deflects the distal end of each protrusion 28 b . the neck portion 34 c goes beyond the distal end of each protrusion 28 b ( the distal end line of fig1 ). the neck portion 34 c is attached to the attachment hole 24 of the clip attachment surface 22 ( see fig1 ). as a result , the clip 3 is attached to the first clip mounting seat 2 a of the interior component 1 . when inserting the neck portion 34 c into the attachment hole 24 a , the pair of tongues 28 are deformed . thus , the clip 3 can be mounted to the clip mounting seat 2 a relatively easily . as shown in fig1 , the clip 3 attached to the clip mounting seat 2 a is retained on the clip mounting seat 2 a by a predetermined retaining force . an external force is applied to the clip 3 , and the neck portion 34 c moves from the attachment hole 24 to the guide groove 26 . the neck portion 34 c abuts the distal end 28 a of the tongues 28 . the distal end 28 a of the tongues 28 are of substantially the same arcuate configuration as the inner peripheral surface of the attachment hole 24 . thus , the distal end 28 a of the tongues 28 effectively receive the neck portion 34 c . as shown in fig1 , the tongues 28 are deflected so as to move toward each other to stop the advancement of the neck portion 34 c . as a result , the tongues 28 act as sufficient resistance to the movement of the neck portion 34 c . the tongues 28 can reliably suppress inadvertent detachment of the clip 3 . as shown in fig1 , the larger the external force applied to the clip 3 , the further the tongues 28 are deflected , and the smaller the distance between the tongues 28 . as a result , inadvertent detachment of the clip 3 can be suppressed more securely . when a force larger than the retaining force is applied to the clip 3 , the neck portion 34 c further deforms the tongues 28 . the tongues 28 move away from each other , and the neck portion 34 c passes between the tongues 28 . as a result , as shown in fig1 , the neck portion 34 c passes through the guide groove 26 , and is detached from the clip attachment surface 22 . the clip 3 is removed from the first clip mounting seat 2 a of the interior component 1 . as described above , the clip attachment surface 22 is provided with the attachment hole 24 ( 24 a , 24 b , 24 c or 24 d ), the guide groove 26 and the pair of tongues 28 . the distal end 28 a of the tongues 28 are of the same arcuate configuration as the inner peripheral surface of the attachment hole 24 . when the clip 3 receives a force in the detaching direction , the distal ends 28 a of the tongues 28 receive the neck portion 34 c . the pair of tongues 28 are deflected so as to move towards each other ( see fig1 ). the tongues 28 move forward , i . e ., in the direction in which the neck portion 34 c is detached from the attachment hole 24 . thus , the tongues 28 offer resistance to the movement of the neck portion 34 c , and inadvertent detachment of the clip 3 from the clip mounting seat 2 a is suppressed . when attaching the clip 3 to the clip mounting seat 2 a , the tongues 28 are deflected . thus , the clip 3 can be attached to the clip mounting seat 2 a relatively easily . as shown in fig4 , the tongues 28 have the protrusions 28 b protruding so as to reduce the groove width of the guide groove 26 . as shown in fig9 , in the state in which the deflected tongues 28 abut both edges 26 a of the guide groove 26 , the distance between the protrusions 28 b is smaller than the diameter of the neck portion 34 c . when attaching the clip 3 to the first clip mounting seat 2 a , the neck portion 34 c is inserted toward the attachment hole 24 , and the neck portion 34 c goes beyond the distal ends of the protrusions 28 b of the tongues 28 . as a result , the worker can feel the attachment of the clip 3 to the clip mounting seat 2 a from the fingers with which the anchor body 32 is gripped . as a result , it is possible to prevent the worker from forgetting to attach the clip 3 to the clip mounting seat 2 a . fig1 to 26 show a clip mounting seat 102 which allows the clip 3 to be detached for maintenance more easily than the clip mounting seat 2 shown in fig3 to 17 . the tongues 28 of the clip mounting seat 102 have distal ends 28 e as shown in fig1 instead of the distal end 28 a shown in fig4 . the distal ends 28 e are substantially linear , and are directed to the center of the attachment hole 24 . each distal end 28 e has a first portion 28 c near the guide groove 26 and a second portion 28 d far from the guide groove 26 . the second portion 28 d extends near the extension of the arcuate line at the inner peripheral surface of the attachment hole 24 . the first portion 28 c extends on the outer side of the extension of the arcuate line . as a result , the distal ends 28 e can also cause the same effect as the distal end 28 a shown in fig4 . as shown in fig2 to 26 , when the clip 3 receives a force in the detaching direction , the neck portion 34 c moves from the attachment hole 24 to the guide groove 26 . the neck portion 34 c abuts the second portions 28 d of the distal ends 28 e of the tongues 28 . the second portions 28 d receive the neck portion 34 c , and the tongues 28 are deflected so as to move towards each other . the tongues 28 act as resistance to the detachment of the neck portion 34 c from the clip mounting seat 102 . as a result , it is possible to suppress inadvertent detachment of the clip 3 from the clip mounting seat 102 . when a further force is applied to the clip 3 , the tongues 28 are deflected , and the neck portion 34 c reaches the first portions 28 c of the distal ends 28 e . the first portions 28 c are pushed by the neck portion 34 c , and the tongues 28 are deflected so as to move away from each other . the first portions 28 c have an angle causing them to be further directed to the guide groove 26 than the distal end 28 a shown in fig4 . as compared with the distal end 28 a shown in fig4 , it is more difficult for the distal ends 28 e to offer resistance to the passing of the neck portion 34 c through the guide groove 26 . thus , as compared with the embodiment of fig4 , it is possible for the neck portion 34 c to be passed through the guide groove 26 by a smaller force . as compared with the embodiment of fig4 , the clip 3 can be detached from the first clip mounting seat 102 of the interior component 1 by a smaller force . thus , plastic deformation of the tongues 28 is suppressed . as a result , it is possible to reuse the clip mounting seat 102 . while the embodiments of invention have been described with reference to specific configurations , it will be apparent to those skilled in the art that many alternatives , modifications and variations may be made without departing from the scope of the present invention . accordingly , embodiments of the present invention are intended to embrace all such alternatives , modifications and variations that may fall within the spirit and scope of the appended claims . for example , embodiments of the present invention should not be limited to the representative configurations , but may be modified , for example , as described below . the interior component 1 may be a door trim or various other kinds of resin molding . the above embodiments may be applied to the attachment of various exterior components instead of the interior component 1 . the tongues 28 have the arcuate distal end 28 a or the linear distal ends 28 e . alternatively , each tongue 28 may have a v - shaped distal end or a grooved distal end . the clip attachment surface has a pair of tongues . alternatively , the clip attachment surface may have one or more than two tongues .
