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, and a pressing force generating means that generates an axial pressing force in accordance with the relative rotation of the two rotating members and applies it to the friction clutch. ,
The pressing force generating means is configured to include an actuating piston that is slidable liquid-tightly in the axial direction between the two rotary members and is integrally rotatable with the outer rotary member and faces the friction clutch; a retainer that is integrally rotatably provided at the open end of the retainer and forms a fluid chamber in which a viscous fluid is sealed, having a predetermined distance between the retainer and the actuating piston in the axial direction; and one or more retainers that extend in the radial direction. A driving force transmission device comprising a rotor having a vane portion and rotatably assembled to the inner rotating member in the fluid chamber, wherein a threaded portion is provided on the inner periphery of the open end of the outer rotating member. At the same time, a threaded part is provided on the outer periphery of the outer end of the retainer to be screwed into the threaded part so as to be able to move forward and backward, and after the retainer is screwed onto the outer rotating member, both of them are connected to each other by spot welding. A driving force transmission device characterized by:
