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 the frictional engagement force in accordance with the axial pressing force, and a pressing force generating means that generates an axial pressing force in accordance with the relative rotation of both rotating members and applies it to the friction clutch, an actuating piston that faces one side of the friction clutch and is assembled to be able to slide liquid-tightly in the axial direction between the two rotary members and to rotate integrally with the outer rotary member; a fluid chamber formed between the outer rotating member and the actuating piston and having a predetermined interval in the axial direction and containing a viscous fluid; and one or more vanes extending in the radial direction; In a driving force transmission device constituted by a rotor that is integrally rotatably assembled to a member, the rotor is fitted into an annular groove provided on the outer periphery of the actuating piston so that the outer periphery of the actuating piston and the inner surface of the outer rotating member are connected. A driving force transmission device characterized in that a seal ring made of an elastic member that seals the circumference liquid-tightly has a substantially D-shaped cross section with a planar inner circumferential side and an arcuate outer circumferential side.
