Abstract
A damper mechanism is provided to suppress the enlargement of a prescribed angle in a damper mechanism. A clutch disk assemblyhas an input rotary member, a spline hub, a damper section, a large friction mechanism, a friction suppressing mechanism, and an elastic member. The spline hubis arranged to rotate relative to the input rotary member. The damper sectioncouples the input rotary memberand the spline hubtogether rotationally. The large friction mechanismcan generate friction when the input rotary memberand the spline hub rotate relative to each other. The friction suppressing mechanism is a rotational gap θACp for preventing the large friction mechanism operating within a prescribed angular range. The elastic membersoftens the impact between the members that touch against each other at the end of the prescribed angular range.
