Abstract
In order to provide a reliable connection between a circular plate mounted on a hub and a friction material having a pair of oppositely faced friction surfaces extending in the axial direction in a clutch disc, a sub plate is secured to the circular plate. This permits the interposition therebetween of frictional material in such a manner that a plurality of axial openings are provided in the circular plate and the sub plate and the friction surfaces project from each opening in opposite axial direction.
