ABSTRACT:
A damper disc comprises a hub to be connected to a shaft and having a radial flange; a pair of side plates disposed at both sides of the hub flange; sub-plates disposed relatively rotatably between the hub flange and the side plates; torsion springs circumferentially connecting the flange and the side plates; a first friction mechanism disposed between the hub and the sub-plates; and a second friction mechanism disposed between the side plates and the sub-plates. Said first friction mechanism includes a cylindrical bushing fitted into the sub-plate and a cone spring. The bushing is provided at an end with a radial flange which is pressed to the hub flange by the cone spring disposed between the sub-plate and the bushing flange. The sub-plate and the bushing are prevented from relative rotation.
