Abstract
A damper disc, in which first friction washers for generating a large hysteresis torque are provided on opposite sides of a flange of a spline hub and a substantially annular disc-like intermediate member is provided so as to be pressed on an outside of a friction washer. A projection projecting toward a side plate is formed on the intermediate member. The projection is fitted into the side plate in such a manner that the intermediate member and side plate can slide freely with respect to each other within a specified torsion angle. A second friction washer generating a small hysteresis torque is provided between the intermediate member and the side plate.
