Claims

[Scope of utility model registration request]

A hub 1 and a vibrating ring 2 inserted into an annular sealed chamber in the hub 1 are connected via an elastic body 3, and a viscous fluid 7 is introduced into the gap between the vibrating ring 2 and the chamber wall 5 of the sealed chamber. In the sealed viscous rubber damper, an expansion ring 6 is fixed to the chamber wall 5 in close opposition to the vibration ring 2, and any one of the hub 1, the vibration ring 2, and the expansion ring 6 is expanded with the other member. A viscous rubber damper characterized by being made of materials with different coefficients and generating a difference in thermal expansion in the direction of narrowing the gap between the vibration ring 2 and the expansion ring 6 at high temperatures.
