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 frictional engagement force in accordance with thrust; a viscous resistance generating means that generates a viscous resistance in accordance with the relative rotation of the two rotating members; and a viscous resistance generating means located between the viscous resistance generating means and the friction clutch; a pair of cam members that are integrally rotatably provided on one of the rotating members and rotate relative to each other in accordance with the viscous resistance force; and a cam follower that is interposed between these cam members and acts to separate the cam members from each other. a viscous fluid chamber defined by the other cam member of both cam members of the thrust converting means in the outer rotating member; a first fin concentrically provided with a large number of fin parts protruding into the fluid chamber; and each fin part of the first fin provided in the fluid chamber so as to be integrally rotatable with the other of the rotating members. and a second fin having a plurality of fins that are fitted concentrically and alternately, and a sealing member that liquid-tightly seals between the viscous fluid chamber and the accommodation chamber of the friction clutch is provided on one of the cam members. and a power transmission device, characterized in that it is provided on one or both sides of the second fin.
