Claims

[Claims for Utility Model Registration] (1) First and second transmission members arranged so as to be relatively rotatable, an operating chamber filled with viscous fluid, and a first transmission member engaged with the first transmission member. A set of plates,
a viscous cut spring having a first set of plates and a second set of plates alternately arranged within the working chamber and engaged with a second transmission member, the first and second plates; At least one of the engagement parts of the set includes notches formed at equal intervals in the circumferential direction, an engaging element passing through the notch of each plate in the axial direction, and a connection between the engaging element and the notch. and means for increasing the contact area in the axial direction. (2) first and second transmission members arranged to be relatively rotatable, an operating chamber filled with viscous fluid, and a first plate set engaged with the first transmission member;
a viscous cut spring having a first set of plates and a second set of plates alternately arranged within the working chamber and engaged with a second transmission member, the first and second plates; At least one of the engagement parts of the pair includes cutouts formed at equal intervals in the circumferential direction, and an engagement element that penetrates in the cutout part of each plate in the axial direction. A viscous coupling ring characterized in that an engaging means for engaging is formed, and the plates forming the engaging means are integrally connected to each other in the rotational direction.
