PURPOSE:To promote movement of liquid between liquid chambers, to provide a high damping function during relatively high vibration, and to decrease vibration transmissivity during fine vibration, by a method wherein the side walls on both sides of each of liquid chambers which are partitioned with outer and inner cylinders and resilient materials are curved inwardly. CONSTITUTION:A plurality of liquid chambers 4 are partitioned by means of inner and outer cylinders 1 and 2 and rubber resilient materials 3, and the liquid chambers 4 are intercommunicated through an orifice 5. Side walls 3b are stretched in a direction, extending at right angles with an axis, to the rubber resilient materials 3 with a specified distance therebetween, the side walls are curved inwardly, and the interior of the liquid chamber 4 is sealed with liquid 6. This constitution promotes movement of the liquid 6 between the liquid chambers 4 during relatively high vibration, provides a high damping function, and enables reduction of vibration transmissivity during fine vibration by reducing a spring constant. |
