摘要：PROBLEM TO BE SOLVED: To increase the quantity of imbalance allowable during rotation and to use a rotor even when its own weight is large by installing a means for positioning a driving device in the axial direction. SOLUTION: A viscoelastic body 4 molded from vibrationproof rubber having elasticity and viscosity and a lifting tool 7 made of a wire rope or a piano wire are arranged in parallel to a driving device 5. By connecting a housing 3 with the bottom surface of the device 5 by the lifting tool 7, the device 5 has horizontal freedom to be vibrated horizontally and to be positioned axially by being restricted vertically. An adjustment mechanism 8 using a screw pitch for operating the length of the tool 7 is fitted to the end of the tool 7. A spring coefficient in which the spring coefficient of the viscoelastic body 4 and the spring coefficient of the tool 7 are combined is made smaller than the spring coefficient of a rotary shaft 6.
