An input member (10) is provided around an output hub (1) in a damper disc, and a pair of diaphragm springs (15) on both axial sides of the input member (10), said diaphragm springs (15) being supported on the input member (10) via a fulcrum means (20, 30). A cam means (4) provided between the inner circumferential portions of the diaphragm springs (15), has an output cam member (3) connected integrally to a hub (1), and a pair of input cam members (6) engaged with the diaphragm springs (15) in the axial direction. The output and input cam members (3, 6) are engaged so that the input cam members (6) are moved axially and away from each other when the cam members (3, 6) are rotated relatively to each other, and the input member (10) is connected to the input cam members (6) so that these members (10), (6) cannot be turned relatively to each other. The reaction force due to the elastic deformation of the diaphragm springs (15) is prevented from being applied as bending moment to the input member (10). |
