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 rotary member and the actuating piston, the fluid chamber having a predetermined interval in the axial direction and containing a viscous fluid; and one or more vanes extending in the radial direction; A drive force transmission device comprising: a rotor housed so as to be rotatable relative to a rotor; a retainer disposed between the outer rotating member and the other side of the friction clutch and facing the friction clutch; a spring member interposed between the retainer and the outer rotating member, the spring member biasing the retainer with a predetermined force to abut the friction clutch and forming a predetermined amount of clearance between the outer rotating member and the retainer; A driving force transmission device characterized by:
