PROBLEM TO BE SOLVED: To prevent a resin shaft from being shaven off by a metal stopper when the stopper is incorporated in the resin shaft. SOLUTION: The stopper 11 consists of deformation parts 22 and engagement pawl parts 23. The deformation parts 22 are formed by being bent from the edge of the insertion hole 21 of the stopper 11 to the opposite side of the insertion direction G of a shaft 3 and returned to the insertion direction G of the shaft 3. The engagement pawl parts 23, extended from the top end of the deformation parts 22 to the insertion direction G of the shaft 3 farther than a spring contact part 20, is elastically engaged with the engagement parts 18 of the shaft 3. Consequently, the resin shaft 3 can be prevented from being shaven off by the stopper 11 when the stopper 11 is built in the resin shaft 3. COPYRIGHT: (C)2009,JPO&INPIT
