PURPOSE:To satisfy both dynamic spring character in high frequency range vibration and damping character in low frequency range vibration by forming a connecting passage connected to both liquid chambers in a rubber elastic body apart from an orifice while putting a movable valve which moves as liquid moves in the connecting passage. CONSTITUTION:A movable valve 16 in a connecting passage 14 permits liquid movement with moving little because of small amplitude in a case of micro vibration, therefore the same prevents the dynamic spring character from getting higher. On the contrary, in a case of relatively large vibration, because of large amplitude the same moves and regulates liquid movement in this route and makes a route via an orifice 12 the only route to pass through therefore damping character can be made to exhibit fully. |
