PURPOSE:To obtain the above ring capable of revolving a ring rotator in high speed for a long time, by fitting a spherical, cylindrical or conical rotator between a transmission plate provided on the ring rotator and a guide plate provided on the ring holder. CONSTITUTION:A ring rotator 4 is prepared by providing the ring main body 2 having a hook 1 with a ring-shaped transmission plate 3, while a ring holder 8 is prepared by providing the ring holder main body 5 with a ring-shaped vibrator 6 and guide plate 7. A rotator 9 supported by a support 10 is fitted between said transmission plate 3 and guide plate 7 so as to be free to revolve, and the rotator 9 is made to revolve by the ultrasonic vibration produced by the vibrator 6, thus effecting high-speed revolution of said rotator. |
