Abstract:
A pressed pulley is provided of which the inner diameter of an inner tubular portion can be increased without changing the outer diameter of an outer tubular portion. The pulley includes an annular connecting portion (13) connected to an end of the outer tubular portion (11) around which a belt is wound and an end of the inner tubular portion (12). The connecting portion is an annular bent portion having a circular arc-shaped section and formed with an inner circular arc-shaped surface (15) having a constant radius of curvature and connected to the radially inner surface of the outer tubular portion (11) and the radially outer surface of the inner tubular portion (12) through respective tangential lines.
