Claims

[Scope of utility model registration request]

It is disposed between a pair of rotating members that are coaxially and relatively rotatably positioned, and is actuated by the relative rotation of both rotating members to generate and apply a frictional engagement force that connects the two rotating members so that power can be transmitted. a frictional engagement force generating means for increasing or decreasing the frictional engagement force by a pressing force; and a pressing force generating means for generating a pressing force corresponding to relative rotation of both rotating members and applying it to the frictional engagement force generating means. , the pressing force generating means is an actuating piston which is slidable in the axial direction in a fluid-tight manner between the two rotary members and is assembled to one of the rotary members so as to be integrally rotatable and abuts the frictional engagement force generating means. , a retainer that is provided on the one rotary member in a liquid-tight manner so as to be rotatable together with the rotary member and that forms a fluid chamber in which a viscous fluid is sealed with a predetermined spacing between the retainer and the actuating piston in the radial direction; a rotor having one or more vane parts extending to the fluid chamber, the rotor being integrally assembled with the other rotating member in the fluid chamber, and dividing the fluid chamber into a plurality of sections in the circumferential direction by the vane parts; In the power transmission mechanism, the actuating piston or the retainer is pressed toward the rotor by a spring member, and the spring member is a spring member that reduces the pressing force when a predetermined temperature is reached. mechanism.
