PURPOSE:To hold a dampering effect and a shrink-fitting performance in a nonmetallic retainer ring by forming a damper in an integral ring type metal damper ring, and disposing it through a thermal insulator in the bore side of the nonmetallic retainer ring. CONSTITUTION:A damper is formed in an integral ring type metal damper ring 1 and disposed in the bore side of a nonmetallic retainer ring 2, and a thermal insulator 3 is provided between the rings 2 and 1. Thus, an expanding force and a current circuit are formed of the ring 1, and a dampering effect and a shrink- fitting performance are held in the ring 2. |
