PROBLEM TO BE SOLVED: To improve hydraulic pressure absorbing capacity and improve endurance strength by increasing the pressure receiving area of a rubber film-form flexible member on which deformation is repeatedly effected. SOLUTION: An insulator 4 formed of vibration isolating rubber material is arranged between an upper coupling member 91 coupled on the vibration body side and a lower coupling member 95 mounted on the car body side. A main chamber 5, an auxiliary chamber 6, and an air chamber 8 are arranged in series at an insulator 4. An annular orifice 3 is provided to intercouple the main chamber 5 and an auxiliary chamber 6. A partition plate 2 is provided to partition the main chamber 5 and the auxiliary chamber 6 from each other. A rubber film-form flexible member 1 is installed at the central part of the partition plate 2. Arrangement of the flexible member 1 is effected in a state to be arranged eccentrically by a given amount E from the central point of an annular ring. |
