MOTORCYCLE COMPRISING A CUSHION CONNECTING ROD
FIG6 is an enlarged view of a portion of a dashed circle shown in FIG5
The endless fiber-reinforced plastic 50 is configured as follows. The long beltlike material (see FIG6) formed by solidifying the fiber material such as carbon fibers and glass fibers by a synthetic resin is wound around the surface of the metallic member 60 by a plurality of times. The direction of the fiber material of the long beltlike material is formed along its longitudinal direction. FIG6 is an enlarged view of a portion of a dashed circle 200 shown in FIG5. The fiber-reinforced plastic 50 is configured in such a manner that after a film adhesive 52 is put on the surface of the metallic member 60, the long beltlike material 51 is wound by a plurality of times (for example, 10 times) from a winding starting point S until a winding ending point G. In this way, since the fiber-reinforced plastic 50 is configured by winding the long beltlike material 51, the incisal edges of the material are less likely generated, and the yield in a manufacturing process of the fiber-reinforced plastic 50 can be improved. Also, a winding process is mechanized, thereby eliminating a process to manually putting the materials on. As a result, production man-hours can be reduced. After the beltlike material 51 is wound, the whole is heated, so that the thermosetting adhesive 52 is hardened, and each portion between the mutual beltlike materials 51 is fixed.
