Abstract
A damper disc applicable to a clutch disc comprising a hub flange; a pair of annular side plates; a pair of annular sub-plates disposed between the side plates and the flange; stud pins connecting the subplates together; recesses formed at middle portions of the side edges of the openings in the flange, each stud pin passing through each recess with a space corresponding to a torsion angle for first hysteresis torque between the stud pin and the side edge of the recess; stop pins connecting the radially outer portions of the side plates together; notches formed at outer edges of the openings in the flange, each stop pin passing through each notch with a space corresponding to a maximum torsion angle between the stop pin and the side edge of the notch; and thereby, a maximum torsion angle can be set large, and the sub-plates can operate stably.
