Abstract
A clutch disk is provided of the type comprising a hub to be coupled with a torque output shaft, an inner hub flange fixed integrally to the hub, an outer hub flange disposed concentrically on the outside of the inner hub flange so that it can rotate within the extent of a predetermined angle by means of splines with respect to the inner hub flange, main and auxiliary disk plates disposed on each side of both the flanges which are to be coupled with a torque input shaft, and provision for a hysteresis effect including thrust material provided between the flanges and the main and auxiliary disk plates, which is characterized in that plate material for covering a torsion section cutout and a spline section formed between the inner and outer hub flanges is disposed between the thrust material for providing the hysteresis effect and both the hub flanges, and the plate material has a fixing section for making the plate material rotate together with the inner hub flange, whereby a stable hysteresis is obtained.
