Claims

[Claims for Utility Model Registration] A clutch facing that is pressed between a flywheel and a pressure plate, a disk plate and a sub-plate to which the facing is fixed, and a clutch facing that is integrally attached to the input shaft of a transmission in the rotational direction. and a first damper incorporating a spline-fitted clutch hub slidably in the axial direction and a first spring with a low spring constant that acts from the beginning of the torsional angle.
In a vehicle clutch disk equipped with a second or subsequent damper incorporating a second or subsequent spring with a high spring constant that acts at a predetermined torsion angle or more, the vehicle changes from a deceleration state to an acceleration state and from an acceleration state to a deceleration state. A cam member is provided that disables the first damper during at least one of the transient states, and the cam member is rotatable by a pin with respect to one of the members constituting the second and subsequent dampers. 1. A clutch disk for a vehicle, further comprising a friction device disposed between said cam member and one of the members.
