PURPOSE: To simplify constitution, and facilitate assembling work by directly bringing a stopper member into contact with a compression side locking part at compression time, and intergrally constituting the compression side locking part with a partition plate. CONSTITUTION: A liquid chamber 24 is divided into two parts of a liquid chamber 31 on the vibration control base body 12 side and a liquid chamber 32 on the diaphragm 14 side by a partition plate 26 installed on the inner periphery of a main body metal fitting 10, and liquid can mutually flow in both liquid chambers 31 and 32 by an orifice 54 of the partition plate 26. A stopper member 34 arranged in the liquid chamber 31 moves to the vibration control base body 12 side at elongation time, and a horizontal part 34b of the stopper member 34 comes into contact with a tensile side locking part 40 of a vibration control base body 12. A further movement of the stopper member 34 is checked by this contact, and excessice elongation of the vibration control base body 12 is prevented. The stopper member 34 moves to the partition plate 26 side at compression time, and the horizontal part 34b of the stopper member comes into contact with a compression side locking part 46 of the partition plate 26. Therefore, a further movement of the stopper member 34 is checked, and excessive compression of the vibration control base body 12 is prevented. |
