PURPOSE:To secure an imbalanced absorption action effective for the wide variation in imbalance amounts by providing an annular chamber with a liquid and a sphere being contained in sealed manner as an imbalance absorptive medium in a rotary tank. CONSTITUTION:When imbalance amounts are within the limiting point of imbalance absorption by a sphere 12, the sphere 12 exhibits its excellent ball balancing effect to effectively reduce the vibration of a rotary tank 4. Also, when the imbalance amounts exceed the limiting point of imbalance absorption, which is the limit of the ball balancing effect, a liquid W as a balancing weight is applied to the sphere 12, whereby suppressing the lowering of imbalance absorptive capability. In this way, the balancer 8 exhibits its effective imbalance absorption action for the wide variation in imbalance amounts. |
