Claims

[Scope of utility model registration request]

A pair of rotating shafts are arranged on the same axis and torque is input to one of them. A housing defining a cylindrical space around a rotating shaft, a plurality of inner plates that are movably engaged with the other rotating shaft and facing each other at a predetermined interval, and between each of the inner plates. In a viscous coupling ring, the viscous coupling includes an outer plate that is arranged at regular intervals and that engages an inner wall of the housing in an axially movable manner, and a viscous fluid filled between the inner plate and the outer plate, a cam surface having a predetermined shape formed on the inner end surface of the housing, and a cammed surface having the same shape opposite to the cam surface;
A holding member that has a predetermined play in the circumferential direction and is movable in the axial direction fits into the inner circumferential surface of the housing and holds the outer plate, and the cammed surface of the holding member and the cam surface of the housing engage. A viscous cut spring characterized by comprising an elastic member that exerts a biasing force as shown in FIG.
