PURPOSE:To suitably absorb vibration by providing an orifice separately from a shaft piercing through a liquid chamber, thereby to always ensure movement of a fluid. CONSTITUTION:The middle portion of a connecting shaft 26 pierces through an intermediate film 24, and a ring 28 is fixed to the intermediate film 24 to move in the axial direction in relative to the outer periphery of the connecting shaft 26. Therefore, the ring 28 corresponds to the outer periphery of the connecting shaft 26, so that the intermediate film 24 moves relatively to the connecting shaft 26. Accordingly, even if the connecting shaft 26 moves, the intermediate film 24 is kept from being pulled to move by the connecting shaft 26, so that the expansion and contraction of an upper small liquid chamber 22A and a lower small liquid chamber 22B are ensured to suitably absorb vibration. |
