The cushioning plate 21 has a corrugated form allowing elastic deformation. The first sintered alloy pad 22 is arranged at the cushioning plate 21. The second sintered alloy pad 23 is fixed to the driven plate 20 having an outer peripheral edge bent for fixing the second sintered alloy pad 23. The rivet 32 has an end engaged with the second sintered alloy pad 23, is axially movable, and has the other end for fixing the cushioning plate 21 and the first sintered alloy pad 22. In a second embodiment, a pair of first and second cushioning plates 120 and 121 are opposed to each other at an outer peripheral portion of the clutch disk assembly. Sintered alloy pads 122 and 123 fixed at outer surfaces of the first and second cushioning plates 120 and 121.
