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 both rotating members so that torque can be transmitted. A friction clutch that increases or decreases the friction engagement force according to the pressing force, and a pressing force generating means that generates a pressing force corresponding to the relative rotation of both rotating members and applies it to the friction clutch, the pressing force generating means ,
an actuating piston that is slidable in the axial direction in a fluid-tight manner between the two rotary members and is integrally rotatably assembled to one of the rotary members and faces the friction clutch; a retainer which is provided so as to be integrally rotatable and has a predetermined distance between it and the actuating piston to form a fluid chamber in which a viscous fluid is sealed; and one or more vane portions which extend in the radial direction. In a power transmission mechanism comprising a rotor that is integrally rotatably assembled to the other rotating member in a fluid chamber, the retainer is provided in the retainer and communicates with the fluid chamber to inject viscous fluid into the fluid chamber. In the injection hole, the volume of the opening on one side of the fluid chamber is made substantially zero, or a hole with substantially the same volume as the opening side is provided on the other side of the fluid chamber, facing the injection hole. A power transmission mechanism characterized by being provided with.
