ABSTRACT:
In one embodiment, a pair of spring seats (32) are used at opposite ends of a small coil spring (6) disposed between a power input rotary member and a power output rotary member. Each spring seat (32) includes a receiving side surface for receiving the small coil spring and a contacting surface (36). The contacting surface (36) is formed with slanting portions with V-shaped cross sections (37, 38) mutually perpendicular. The power input rotary member and the power output rotary member each contact a respective slanting section of one of the slanting portions. In another embodiment, a spring seat (40) is provided with a first support portion (43) and a second support portion (44) such that the orientation of the spring seat (40) determines a phase or orientation of the power input rotary member with respect to the power output rotary member. In a third embodiment, a friction element is formed of resin and includes a friction adjusting element (20). The friction adjusting element (20) is provided in the friction generating surface of the body portion (15a) of the friction element by molding and is intended for modifying the friction coefficient thereof. In a fourth embodiment, a first friction element (14) includes a friction generating surface having a coefficient of friction which differs from that of a friction generating surface of a second friction element (15).
