PURPOSE:To maintain and improve a vibration control characteristic by reducing even high frequency vibration that cannot be reduced effectively by a passage to be an orifice. CONSTITUTION:An outer cylinder 16 is disposed in the ring part 14 of a fitting frame 12. An intermediate cylinder 22 with an elastic body 28 bonded thereto, and an intermediate block 24 with passages 56, 56, 64 formed to communicate liquid chambers are fitted into the outer cylinder 16. A cover plate 80 with an elastic plate 86 bonded thereto is fitted to the intermediate block 24, and the internal pressure increase of a liquid chamber generated in association with the deformation of the elastic body 28 is prevented by the deformation of the elastic plate 86. Vibration can be thereby reduced effectively even in the case of especially high frequency vibration being generated. |
