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 a friction engagement force in accordance with the thrust; a viscous resistance generating means that generates a viscous resistance in accordance with the relative rotation of the two rotating members; and a viscous resistance generating means located between the viscous resistance generating means and the friction clutch; Thrust converting means having a pair of cam members that rotate relative to each other in response to viscous resistance, and a cam follower that is interposed between a plurality of cam surfaces of these cam members and urges both of them to move away from each other in the axial direction when the two cam members rotate relative to each other. A power transmission device, characterized in that the inner and outer sliding contact surfaces of both the cam members are formed into protruding surfaces that extend in an arc shape in the axial direction with respect to the sliding contact surfaces that oppose the sliding contact surfaces.
