Abstract
A pulley is made from a metal plate which is easy to manufacture, inexpensive in manufacturing cost, light weight and sufficient strength by using a press forming technique. The pulley has a thin tubular boss portion and a disk shaped body portion which are integral. The boss portion may have a reinforcing flange at one open end portion. The reinforcing flange aids in providing sufficient strength against the tightening force of a nut which is screwed onto a shaft inserted into the boss portion, and also disperses the tightening force. Further, the pulley may have formed integrally on the boss portion a key member.
