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 driving force transmission device comprising a pressing force generating means for applying, and 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. In,
a first annular oil groove extending in the circumferential direction on one side of the retainer ring that contacts the friction clutch and the other side that contacts the outer rotating member;
A plurality of second oil grooves are provided at equal intervals in the circumferential direction, extend in the radial and outward directions, and have a circumferential width narrower than the circumferential width of the retainer ring receiving surface of the outer rotating member, and A driving force transmission device characterized in that these second oil grooves are disposed on both side surfaces of the retainer ring so as to be displaced from each other in the circumferential direction.
