Abstract
A pair of spring seats (,) are used at opposite ends of a small coil spring (,) disposed between a power input rotary member and a power output rotary member. Each spring seat (,) includes a receiving side surface for receiving the spring and a contacting surface (,). Each contacting surface (,) is formed with four slanting surfaces that slant inward toward a central portion of the contacting surface. The intersections of the four slanting surfaces of each spring seat define two intersecting V-shaped grooves (,). The power input rotary member and the power output rotary member contact respective portions of one of the V-shaped grooves (,) of each spring seat. Engagement between the rotary members and the engaged V-shaped grooves restricts movement of the spring seats (,).
