Claims

[Scope of claim for utility model registration] A metal reinforcing ring is embedded inside the rubber ring,
In a lip type seal in which the inner lip of the rubber ring contacts the rotating shaft to seal the rotating shaft, a plurality of bimetallic metal plates are attached to the axial end of the reinforcing ring along the circumferential direction. This bimetallic metal plate is located on the outer peripheral side of the contact area of the lip part, and works to reduce fluctuations in the contact force of the lip part due to temperature rises and falls.
