SHAFT MEMBER

摘要

A component (14) of a material which is different from that of a shaft (12) is firmly attached to one end of the shaft (12). The component (14) is provided with an axial projection (15) corresponding to a recess (13) formed in the outer peripheral surface of the shaft (12), and a hold (16) is formed in the projection (15) to receive a retainer member (17). The retainer member (17) enables the retention of a component (20) such as a pulley or the like, so that the component (20) does not rotate about the shaft (12).
