Abstract
A spring seat 51 adapted to support a large coil spring 34 to absorb and to dampen torsional vibrations and a small coil spring 35 positioned within the large coil spring 34 having a smaller outside diameter than an inside diameter of the large coil spring 34, includes a seat body 52 supporting an end of the large coil spring 34 and an end of the small coil spring 35 in a compressing direction, a first supporting portion 54 protruding from the seat body 52 in the compressing direction of the small coil spring 35 and supporting an inner periphery of the small coil spring 35, and a second supporting portion 53 formed at an end portion of the seat body to covering partial an outer periphery of the large coil spring 34 and to support an outer peripheral side of a part of the large coil spring 34.

A spring seat being configured to support a large coil spring to absorb and to dampen torsional vibrations and a small coil spring being positioned within the large coil spring having a smaller outside diameter than an inside diameter of the large coil spring, comprising:
- a seat body being configured to support an end portion of the large coil spring and an end portion of the small coil spring in a compressing direction;
- a first supporting portion protruding from the seat body in the compressing direction inside the small coil spring and supporting an inner periphery of the small coil spring;
- and
- a second supporting portion being formed at an end portion of the seat body to cover partially an outer periphery of the large coil spring and to support an outer peripheral side of a part of the large coil spring.
A spring assembly being provided at a window opening of dual rotational members for a torsional damper, and compressed in a rotating direction by the window opening when the dual rotational members relatively rotate, comprising:
- a large coil spring;
- a small coil spring having a smaller outside diameter than the inside diameter of the large coil spring;
- and
- spring seats being arranged at the both ends of the large coil spring and the small coil spring, each spring seat having
- a seat body being configured to support an end portion of the large coil spring and an end portion of the small coil spring in a compressing direction,
- a first supporting portion protruding from the seat body in the compressing direction inside the small coil spring and supporting an inner periphery of the small coil spring, and
- a second supporting portion being formed at an end portion of the seat body to cover partially an outer periphery of the large coil spring and to support an outer peripheral side of a part of the large coil spring.
