PCT No. PCT/JP82/00424 Sec. 371 Date Jun. 21, 1983 Sec. 102(e) Date Jun. 21, 1983 PCT Filed Oct. 29, 1982 PCT Pub. No. WO83/01663 PCT Pub. Date May 11, 1983.A clutch disc for an automobile transmits torque from engine to a transmission through a disc plate, a torsion spring and a hub connected to an output shaft. A bush is press-fitted between the sliding surfaces of the disc plate and the hub to reduce the surface pressure at the sliding surfaces and also to prevent intrusion of dust into the sliding surfaces. The torsion spring and a sub-torsion spring disposed between a hub plate and a friction plate holding the hub plate therein are retained at their both ends in position by means of spring-retaining lugs formed integrally with spring holding portions of the hub plate. Thus, generation of noise from the individual members is prevented.
