To suppress generation of noise due to cavitation disruption without deteriorating vibration isolation property by a simple structure.SOLUTION: A restriction passage 24 includes: a first communication part 26 opened in a first liquid chamber 14; a second communication part opened in a second liquid chamber 15; and a body flow passage 25 for communicating between the first communication part and the second communication part. At least one of the first communication part and the second communication part includes a plurality of pores 26a. A barrier 40 formed with the pores is made of a rubber material.SELECTED DRAWING: Figure 1

    【課題】簡易な構造で防振特性を低下させることなく、キャビテーション崩壊に起因する異音の発生を抑える。【解決手段】制限通路24は、第1液室14に開口する第1連通部26、第2液室15に開口する第2連通部、および第1連通部と第2連通部とを連通する本体流路25を備え、第1連通部および第2連通部のうちの少なくとも一方は、複数の細孔26aを備え、複数の細孔が形成された障壁40は、ゴム材料により形成されている。【選択図】図1
