A damper disc applicable to a clutch disc comprises a hub flange 3; a pair of annular side plates 5, 6; a pair of annular sub-plates 16 disposed respectively between the side plates 5, 6 and the flange 3; stud pins 18 connecting the sub-plates 16 together; recesses 33 formed at middle portions of the side edges of openings 24, 25, 23 in the flange 3, each stud pin 18 extending through said each recess 33 with a spacing corresponding to a torsion angle for first hysteresis torque between the stud pin 18 and the side edge of the recess 33; stop pins 12 connecting the radially outer portions of the side plates 5, 6 together; notches 30 are formed at outer edges of the openings 24, 25, 23 in the flange 3, each stop pin 12 extending through each notch 30 with a space corresponding to a maximum torsion angle between the stop pin 12 and the side edge of the notch 30. Friction damping 15, 17 of differing degree is applied to sub plates and side plates. Three differing sizes 20, 21, 22 of torsion spring are used. <IMAGE> |
