Abstract
A clutch disc including a disc-like annular facing members arrange to front on each other and a cushioning plate corrugated in circumferential direction. Stiffening plates which are disc-like annular bodies having inside and outside diameters approximately identical with those of facing members and on which slotted holes extending nearly in radial direction are made at plural places in circumferential direction, are glued to fronting surfaces of the facing members. The cushioning plate is disposed between the fronting stiffening plates to make convex portions on its both surfaces contact with portions located between the slotted holes of the stiffening plates, and is fastened by rivets to the contacting portions.
