Claims

[Scope of utility model registration request]

A side plate is integrally molded to cover one side of the rim part, rectangular wave-shaped teeth are formed on the circumferential surface of the rim part, and a central part of the side plate projects into the inner cavity of the toothed rim part. In a sheet metal pulley made of a single metal plate formed by molding a bowl-shaped boss mounting plate, a circular reinforcing plate is fitted into the inner cavity of the toothed rim to form the boss mounting plate. The reinforcing plate is inserted into a window drilled in the center thereof, and an annular installation and fixing plate portion formed inside the inner periphery of the reinforcing plate is attached and supported on the inner surface of the side plate in the outer periphery of the proximal end of the boss mounting plate portion; The reinforcing plate is integrally attached and supported to the side plate by welding or gluing key points of the attachment support surface, and the inner circumferential surface of the toothed rim portion integrally molded on the outer circumferential portion of the reinforcing plate. A sheet metal pulley characterized in that a parallel annular support plate part is attached and supported on the inner circumferential surface of a toothed rim part, and the attached support surface is used as a free contact surface.
