A small diameter part (2a) of a support shaft (2) is inserted or pressure-inserted into a through hole (1a) of a handle arm (1) and fixed by caulking so that the support shaft (2) protrudes on the side face of the handle arm (1). A hollow shaft part (3) is rotatably fitted to an outer periphery of a shaft part (2b) of the support shaft 92) through a washer (10). The hollow shaft part (3) is prevented from falling off from the support shaft (2) by an E-ring (12) fitted to the other side of the support shaft (2) through a washer (11). Since the hollow shaft part (3) is arranged to be detachably supported onto the support shaft (2), the frictional resistance in rotation between the support shaft (2) and the hollow shaft part (3) can be reduced through maintenance such as washing and lubrication. |
