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 in which a viscous fluid is sealed; and a vane portion extending in the radial direction; In a driving force transmission device constituted by a rotor that is fitted and assembled so as to be able to rotate integrally, the engagement surfaces of the rotor and the spline portion of the inner rotating member that engage with each other in the rotational direction are aligned with respect to the axis. A driving force transmission device characterized in that it is formed on a tapered surface that slopes.
