Second spring seatseach have a first support component, a second support component, and a reinforcing plate. The first support componentsupports the ends of second coil springin the rotational direction. The second support componentextends in the rotational direction from the first support componentand supports the end of the second springin the radial direction. At least part of the reinforcing plateis embedded in at least one of the first and second support componentsand. The reinforcing platedirectly or indirectly supports the end of the second springalong with the first and second support componentsand

Spring seat and damper disk assembly

Second spring seatseach have a first support component, a second support component, and a pair of reinforcing components. The first support componentssupport the ends of second coil springsin the rotational direction. The second support componentsextend in the rotational direction from the first support components, and support the ends of the second coil springsin the radial direction. The reinforcing componentslink the first support componentsand the second support components, and extend in the radial direction from the second support components

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 &#x3b8;ACp 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.

The large friction mechanism can generate friction when the input rotary member and the spline hub rotate relative to each other. The friction suppressing mechanism is a rotational gap &thgr;ACp for preventing the large friction mechanism operating within a prescribed angular range. The elastic member softens the impact between the members that touch against each other at the end of the prescribed angular range.
