PINCH DETECTION SENSOR
FIG4B is a cross-sectional view showing the holding member and its surroundings in a compressed condition when acted on by a pressure  FIG3 is a perspective view showing a pressure sensitive sensor 5
Gaps are being formed between the holding portion 62 and the side surfaces 30b and 30c, respectively, of the recessed portion 30. As shown in FIG4B, those gaps act as clearance spaces for the holding portion 62 when the holding member 6 is compressed. The first pressure sensitive sensor 5A is sensitive to the pressure in the event of pinch in the sliding doors 11A and 11B, by being compressed by the holding member 6 being compressed from the opening side of the recessed portion 30, in such a manner as to bring the plurality of conductor wires 52 into contact with each other.  FIG3 is a perspective view showing the pressure sensitive sensor 5. The pressure sensitive sensor 5 includes a tube 51 which is formed of a tubular elastic body, and a plurality of conductor wires 52 which are spaced apart from each other in an inner side of that tube 51. More specifically, two conductor wires 52 are being helically held on an inner surface of the tube 51 while being partially exposed, with a space 50 being formed in a central portion of the tube 51. The tube 51 is made of, for example, an insulating rubber material such as silicone rubber or ethylene propylene rubber, and has such elasticity as to be deformed by being acted on by an external force, and restored immediately no external force is exerted.

['1. A pinch detection device, for detecting the occurrence of pinch during closing of one pair of sliding doors, comprising: a first door front edge rubber to be attached to an edge portion in a closing movement direction of one sliding door of the one pair of sliding doors; and a second door front edge rubber to be attached to an edge portion in a closing movement direction of an other sliding door of the one pair of sliding doors, wherein the first door front edge rubber includes a recessed portion, which is open toward the second door front edge rubber, with a linear shape pressure sensitive sensor, which is sensitive to a pressure in the event of pinch, being disposed in that recessed portion.', '2. The pinch detection device according to claim 1, further including a holding member comprising an elastic body with a hollow portion therein, with the pressure sensitive sensor disposed in the recessed portion being accommodated and held in that hollow portion, wherein the holding member integrally includes a base section, which is attached to a bottom surface of the recessed portion and a cylindrical holding portion, which is formed with the hollow portion in a central portion thereof, with a width of the base section in a thickness direction of the one sliding door being wider than a width of the holding portion in the same thickness direction, with the pressure sensitive sensor being positioned in the thickness direction of the one sliding door by the base section, with gaps being formed between the holding portion and side surfaces, respectively, of the recessed portion.', '3. The pinch detection device according to claim  1  or  2,  wherein the first door front edge rubber includes a hollow space in a vehicle exterior side relative to the recessed portion, with a linear shape pressure sensitive sensor, which is sensitive to a pressure from the vehicle exterior side relative to the recessed portion, being disposed within that hollow space.']
