Claims

[Scope of utility model registration request]

A side plate is integrally molded on one side of the toothed rim part, a sheet metal pulley made of a single metal plate with a boss mounting hole penetrated through the center of the side plate, and a boss made of a uniaxial insertion tube having a shaft insertion hole. A plurality of boss rotation preventing grooves are cut out on the periphery of the boss mounting hole of the sheet metal pulley, and the shaft is inserted into the boss mounting hole at one end of the shaft insertion cylindrical portion of the boss member. A small cylindrical portion having a smaller diameter than the outer diameter of the cylindrical portion is provided in series, and by forming the small cylindrical portion, communication between the small cylindrical portion and the shaft insertion cylindrical portion is established.
A step is formed at the step to abut against the circumferential side plate of the boss mounting hole, and a retaining piece corresponding to the boss rotation stopper groove is protruded from the circumferential surface of the small cylindrical portion. Engage the retaining piece of the member into the boss rotation stopper groove of the sheet metal pulley, engage the small cylindrical portion into the boss mounting hole, and apply the stepped portion to the side plate surrounding the boss mounting hole. A sheet metal pulley with a boss, characterized in that the tip of the engaging piece is in contact with the surface of the peripheral side plate of the boss rotation stopper groove, so that the sheet metal pulley is integrated with the boss member.
