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 an axial pressing force; a retainer ring interposed between the outer rotating member and the other side of the friction clutch and receiving the friction clutch via the outer rotating member; an actuating piston that is slidable in the axial direction between the two rotary members in a liquid-tight manner and is assembled to be integrally rotatable with the outer rotary member and faces one side of the friction clutch; A fluid chamber formed between the working pistons and having a predetermined interval in the axial direction in which a viscous fluid is sealed, and one or more vanes extending in the radial direction, and is rotatable integrally with the inner rotating member in the fluid chamber. In the drive force transmission device, the retainer ring has a side surface that contacts the friction clutch,
A first annular oil groove extending in the circumferential direction, and a plurality of second oil grooves provided at equal intervals in the circumferential direction and extending in the radial and outward directions, the circumferential width of the second oil groove being equal to the outer side. A driving force transmission device characterized in that the width is narrower in the circumferential direction of a retainer rig receiving surface of a rotating member.
