Abstract
A clutch disk assembly has an input rotary member , a spline hub , a damper section , a friction mechanism , and a friction suppressing mechanism. The damper section has second springs and a torsion characteristic having a positive side corresponding to when the input rotary member is twisted in a rotational drive direction with respect to the spline hub and a negative side corresponding to when the input rotary member is twisted in an opposite direction. The friction mechanism can generate friction when the input rotary member and the spline hub undergo relative rotation and the second springs exert an elastic force. The friction suppressing mechanism secures a rotational gap &thgr;ACn on only the positive or negative side preventing the second spring from acting on the friction mechanism within a prescribed angular range.
