Abstract
A lightweight damper pulley is provided which can be produced in a simple manner. The damper pulley includes a central portion, a belt retaining portion made of metal plate, and a ring-shaped rubber or elastic member placed therebetween. The central portion includes a cylindrical boss portion to be fixed onto a rotary shaft, a main portion extending radially outwardly from the larger diameter area of the cylindrical boss portion, and a flange bent horizontally from an outer periphery of the main portion. The central portion is integrally formed from a metal plate by press-forming or the like. The flange and the belt retaining portion can have projections which compress the rubber or elastic member to hold it securely in place.
