PROBLEM TO BE SOLVED: To provide a liquid-sealed vibration control device which can decrease a vibration transmission rate by reducing a spring constant of an elastic member.SOLUTION: A liquid-sealed vibration control device 10 has an outer cylinder member 11 connected to a floor of a vehicle, an inner cylinder member 13 connected to an exhaust pipe, and an elastic member 12 which is interposed between the outer cylinder member and the inner cylinder member, and has a liquid chamber 14 sealed with liquid at the inside. In such a liquid-sealed vibration control device 10, annular recesses 15, 16 which are recessed in an axial direction up to a position being the inside of the liquid chamber 14 at a position in a concentric direction are formed at a portion at an internal peripheral side of the liquid chamber 14 in the elastic member 12.

    【課題】弾性部材のばね定数を小さくして、振動伝達率を低減することのできる液体封入制振装置を提供する。【解決手段】液体封入制振装置10は、車体フロアに接続される外筒部材11と、排気管に接続される内筒部材13と、それらの間に介設されるとともに、液体を封入した液室14が内部に設けられた弾性部材12と、を有する。こうした液体封入制振装置10において、その弾性部材12における液室14の内周側の部分に、軸方向における位置が液室14の内側となる位置まで同軸方向に凹んだ、環状の凹部15,16を設けるようにした。【選択図】図2
