PURPOSE:To prevent the axial vibration by interposing a rigid article pushed onto the inner and outer peripheral surfaces by a spring apparatus into an annular space formed into wedge form in the axial direction by the inner peripheral surface of a hydraulic cylinder and the outer peripheral surface of a hydraulic piston. CONSTITUTION:An annular tapered ring 24 having the tapered outer periphery is shrink-fitted onto the hydraulic pistons 20a and 20b, and a wedge-shaped space 31 is formed between the circumferential surfaces of the hydraulic cylinders 18a and 18b. Into the space 31, a wedge-shaped ring 25 which has a tapered surface on the circumference and whose circumference is cut at one part is interposed, and the ring 25 is pushed in the axial direction by a wave- shaped spring 26. Therefore, the vibration in the axial direction of the rotors 4 and 5 can be prevented, and the rigidity in the radial direction can be applied between the hydraulic pistons 20a and 20b and the hydraulic cylinders 18a and 18b.Therefore, the vibration in the radial direction of the rotors 4 and 5 can be prevented. |
