PROBLEM TO BE SOLVED: To ensure durability even under a high temperature and a specified low dynamic spring characteristic. SOLUTION: Between an upper part connection member 9 connected to a vibrator and a lower part connection member 99 connected to a car body side member, a vibration isolating rubber unit 1 inputting vibration from the vibrator and a main chamber 3 charged with a fluid in series to the vibration isolating rubber unit 1 are provided. A subchamber 6 connected to the main chamber 3 through an orifice is provided. So as to wrap the vibration isolating rubber unit 1, a rubber-shaped elastic diaphragm 2 connected to the upper part connection member 9 and a tubular metal fitting 22 connected to the lower part connection member 99 are provided. Inside a space formed by these members is charged with a fluid, the subchamber 6 is formed. The vibration isolating rubber unit 1 is formed mainly of natural rubber, also in outside the elastic diaphragm 2, a protector 21 formed by a plurality of small pieces is provided. |
