ABSTRACT:
In a first embodiment, a clutch disc assembly has a retaining plate 5, a hub 2, a first coil spring 6, a second coil spring 7, and a first friction washer 8. A connecting plate 3 is positioned in an outer circumference of the of the hub 2. The first coil spring elastically couples the connecting plate 3 and the hub 2 in a circular direction. The second coil spring 7 elastically couples the retaining plate 5 and the connecting plate 3 in a circular direction and is more excellent in rigidity than the first coil spring 6. The first friction washer 8 includes a first friction member 13 positioned between the retaining plate 5 and the hub 2, a second friction member 14 positioned between the connecting plate 3 and the retaining plate 5, and a coupling element coupling the first and second friction members 13 and 14 and elastically deformable in axial directions. In a second embodiment, a friction resistance generating mechanism 108, a first friction washer 114 is in contact with a side surface of a flange in a hub 102. A second friction washer 115 is in contact with a side surface of a sub-plate 105 and engages the first friction washer 114 so as to rotate along with it in unity in circular directions and to move relative to it in axial directions. A first conical spring 116 urges the first friction washer 114 toward the flange. A second conical spring 117 urges the second friction washer 115 toward the sub-plate 105. Only one of the first friction washer 114 and the second friction washer 115 has snap projections and stem-like projections which engage a retaining plate 104 so as to rotate along with it in unit in circular directions and to move relative to it in axial directions.
