Abstract
A thrust washer has a protrusion which is formed with a projecting pawl. The rotating member is formed with a through hole, into which the protrusion of the thrust washer is inserted, such that the pawl is projected out on the opposed surface remote from the thrust washer of the rotating member, whereby the upstanding surface of the pawl is used as a stop means. Thus, the thrust washer is positively secured to the rotating member.
