ABSTRACT:
A clutch disc is constructed to achieve superior performance by increasing the allowable torque or the angle of torsion of the damper plate. The clutch disc includes a clutch hub, a disc spring, and the damper plate interposed between the clutch hub and the disc spring. The damper plate is provided with an arc-like slit. In a portion of the slit proximate to the end of the slit at the peripheral or the inner peripheral side of the damper plate, the slit is centrifugally curved or curved toward the clutch axis such that both ends thereof are close to a radius of a concentric circle. According to another aspect of the invention, the damper plate is provided with a plurality of first rivets and a plurality of first rivet holes. The radii of the first rivet holes gradually decrease as the distance between the clutch axis and each hole decreases, whereas the radii increase gradually as the distance between the clutch axis and each hole increases. According to a further aspect of the invention, several damper plates are provided and there is a dislocation between the inner periphery of each damper plate and the periphery of the damper plate in the direction parallel with the clutch axis so that the damper plates have a certain thickness in the direction parallel with the clutch axis.
