<p>Provided is a clutch disc having a superior performance of increasing an allowable torque or an angle of torsion of the damper plate. <??>According to a first aspect, in a portion proximate to an end of a slit 31 at the peripheral or the inner peripheral side of the damper plate 21, the slit 31 is centrifugally curved or curved toward a clutch axis such that both ends thereof are close to a radius of a concentric circle, respectively. According to a second aspect , a damper plate 22 has a plurality of first rivets and a plurality of first rivet holes 254 through 257 formed thereon. The radii (r) of the first rivet holes 254 through 257 gradually decrease as the distance between the clutch axis (C) and each thereof decreases, whereas the radii (r) thereof increase gradually as the distance between the clutch axis (C) and each thereof increases. According to third and fourth aspect , there is a dislocation between the inner periphery of each of annular damper plate 23 and 24 and the periphery thereof in the direction parallel with the clutch axis (C) so that the annular damper plates 23 and 24 have a certain thickness in the direction parallel with the clutch axis (C), respectively. <IMAGE></p> |
