PURPOSE:To obtain a high damping performance for both engine shaking and engine pitching, by dividing laterally the inner space of either of a first and a second liquid chamber or both of them with a separating wall made of elastic rubber into divided liquid chambers, and connecting through both chambers to each other with an orifice structure. CONSTITUTION:A first liquid chamber 6 is divided into a left divided chamber 12 and a right divided chamber 13 with a central separating wall 11 made of elastic rubber 2 extended upward and downward. And the respective divided liquid chambers 12, 13 are connected through to each other with an orifice structure 14 provided on the top side 11 of the wall 11. A second liquid chamber 7 is also divided into a left and a right chambers with a central separating wall 15 made of elastic rubber 2 extended upward and downward. And a through hole or a recession 16 is provided in the vicinity of an eccentric side portion over a side chamber 4 and a partition wall 5, and the partition wall 5 bounding on the second liquid chamber 7 located in the outside of the recession 16 is made thin and expanded to make a diaphragm structure 17 of this portion. Thereby the movement of liquid can be made easy to obtain high damping capacity. |
