Claims

[Scope of utility model registration request]

It is arranged between a pair of rotating members that are coaxially and relatively rotatably positioned, and is actuated by the relative rotation of these rotating members to generate and apply a frictional engagement force that connects both rotating members so that power can be transmitted. A frictional engagement force generation means for increasing or decreasing the frictional engagement force according to the pressing force, and a pressing force generation means for generating a pressing force according to the relative rotation of both rotating members and applying it to the frictional engagement force generation means, an actuating piston in which the pressing force generating means is slidable liquid-tightly in the axial direction between the two rotating members and is integrally rotatably assembled to one of the rotating members, and is opposed to the frictional engagement force generating means; a retainer configured to be integrally rotatable with the one rotary member and to form a fluid chamber in which a viscous fluid is sealed with a predetermined distance between the retainer and the actuating piston; and one or more retainers extending in the radial direction. and a rotor integrally assembled to the other rotating member in the fluid chamber, wherein a pressing force is applied to the actuating piston by a spring member. The actuating piston is separated from the frictional engagement force generating means until the pressing force generated by the pressing force generating means reaches a predetermined value, and the spring member is configured to apply a pressing force to the actuating piston when a predetermined temperature is reached. A power transmission mechanism characterized by employing a spring member that increases the power.
