たことを特徴とする駆動力伝達装置。 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, 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 comprising a rotor integrally rotatably assembled to a member, a vane portion of the rotor is formed to have a length spaced apart by a predetermined amount from an outer circumferential surface of the fluid chamber, and A closing member is attached to the tip of the vane portion of the rotor so as to be movable in the radial direction, and the closing member abuts the outer circumferential surface of the fluid chamber at its tip to eliminate or minimize the gap between the outer circumferential surface and the vane portion. A driving force transmission device characterized in that a closing member is spring-biased radially inward to be separated from an outer circumferential surface of the flow chamber.
