Abstract: <P>PROBLEM TO BE SOLVED: To enhance the sound/vibration performance of a clutch disc assembly by improving a friction generating mechanism which functions upon the compression of a highly-rigid elastic member.  <P>SOLUTION: The friction generating mechanism is for generating friction upon relative rotation between a hub flange 3 and a pair of plates 12 and 13 and has a first friction plate 73 forming a frictional surface between itself and one axial side of the hub flange 3, a cone spring 33 positioned between the first friction plate and the plate 13 for imparting axial energizing forces to both, and a second friction plate 51 forming a frictional surface between itself and the opposite axial side of the hub flange 3. The first friction plate 73 has a protrusion 73b which engages a cutout 13a of the plate 13. The protrusion 73b is axially movable by radially abutting the cutout 13a but is incapable of relative rotation. The second friction plate 51 is incapable of relatively rotating as it is bonded to the plate 12.  <P>COPYRIGHT: (C)2004,JPO
