Claims

[Claims for Utility Model Registration] (1) A rotational direction buffer mechanism provided between a first torque transmitting member and a second torque transmitting member rotatable relative to the first torque transmitting member a coil spring that transmits rotational torque according to a relative rotation angle between the member and the second torque transmission member;
a frictional engagement member that frictionally engages the torque transmission member and the second torque transmission member; and a frictional engagement member that presses the frictional engagement member to transfer the frictional engagement member to the first torque transmission member and the second torque transmission member. In a clutch disk configured with a disc spring that is frictionally engaged with a transmission member, the disc spring has a free spring height that is increased when the temperature is below a predetermined temperature and is decreased when the temperature is higher than the predetermined temperature. A clutch disk characterized by being formed from a shape memory alloy. (2) The clutch according to claim 1, wherein the coil spring is formed of a shape memory alloy that increases its free spring length when the temperature is below a predetermined temperature and decreases its free spring length when the temperature is higher than the predetermined temperature. disc.
