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 in the axial direction in a liquid-tight manner between the two rotary members and is integrally rotatably assembled to one of the rotary members and abuts on 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 that is integrally assembled with the other rotating member in the fluid chamber and partitions the fluid chamber into a plurality of sections in the circumferential direction by the vane portion, the power transmission mechanism comprising: The axial thickness of the vane portion of the rotor is gradually reduced from the base end to the tip end, and the minute gap between both side surfaces of the vane portion and the side surfaces of the operating piston and retainer is reduced at the base end of the vane portion. The power transmission mechanism is characterized by being small and gradually increasing toward the tip.
