Abstract
A lightweight pulley is provided which can be produced in a simple manner at low cost. The pulley has a cylindrical boss portion, an annular main portion which extends radially outwardly from the cylindrical boss portion, and a ring-shaped belt retaining portion. The boss portion and the main portion are integrally formed from a thin metal plate by press-forming, thereby reducing the weight of the pulley, and facilitating the production thereof. The peripheral wall of the boss portion is alternately bent inwardly and outwardly in its peripheral direction to form a plurality of ribs, thus increasing the strength of the boss portion. A method of manufacturing the pulley is also provided.
