Claims

[Scope of utility model registration request]

It is disposed between the inner and outer 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 the two rotating members so that torque can be transmitted. a friction clutch that increases or decreases a friction engagement force in accordance with the thrust; a viscous resistance generating means that generates a viscous resistance force in accordance with the relative rotation of the two rotating members; The thrust converting means includes a pair of cam members that rotate relative to each other in response to a resistance force, and a cam follower interposed between the two cam members, and the viscous resistance force generating means is connected to the thrust converting means within the outer rotating member. a viscous fluid chamber partitioned by one cam member; a first fin concentrically having a number of fins provided on the one cam member and protruding into the fluid chamber; a second fin having a plurality of fin portions that are rotatable relative to each other and are fitted concentrically and alternately with each fin portion of the first fin; A power transmission device characterized by comprising a piston that increases pressure.
