Abstract

A damper disk comprises a pair of side plates at both sides of a flange of a hub splined to an output shaft. Both side plates and the flange are connected each other through torsion springs. One or a pair of sub-plates are disposed between the flange and the side plates. Both side plates are connected together by a stop pin which extends through notches in the flange and the sub-plates. The notches in the sub-plates are shorter than the notch in the flange. Frictional force between the flange 2 and the sub-plate is set stronger than that between the side plates and sub-plates. According to the invention, hysteresis torque changes during torsional operation, thereby, noises during idling of the engine as well as acceleration can be prevented.
