PURPOSE:To improve the dynamic vibration absorbing effect by installing a leaf spring having a weight into a container filled with liquid and obtaining the damping function due to the transfer resistance of the flow rate of the liquid between the liquid chambers partitioned by the leaf spring. CONSTITUTION:Liquid is charged in a sealed container 1, and a leaf spring 4 is arranged so as to laterally vibrate inside. The both edges in the longitudinal direction of the leaf spring 4 are fixed onto the wall of the sealed container 1, and a weight 5 is installed at the center part. The space chambers 8A and 8B partitioned by the leaf spring 4 communicate through a penetration hole 7, and the damping function is developed when liquid flows in the penetration hole 7. The frequency of the vibration system consisting of the leaf spring 4 and the weight 5 can be allowed to accord with the frequency of the vibrating substance, and the frequency of the vibrating substance can be varied and also the amplitude can be reduced. |
