To secure attenuation force against axial vibration and lateral vibration.SOLUTION: Of a second liquid chamber 27, a third liquid chamber 28 and a fourth liquid chamber 29, any two liquid chambers communicate with each other through a first restriction passage 31 formed in an outside attachment member 11, an inside attachment member 12 or a partition member 15; and the residual liquid chamber communicates with a fifth liquid chamber 32 formed in the outside attachment member 11, the inside attachment member 12 or the partition member 15. The residual liquid chamber is divided in a circumferential direction, and the fifth liquid chamber 32 and each liquid chamber divided in the circumferential direction are individually communicated with each other through a second restriction passage 33 formed in the outside attachment member 11, the inside attachment member 12 or the partition member 15.SELECTED DRAWING: Figure 1
【課題】軸方向および横方向の各振動に対して減衰力を確保する。【解決手段】第2液室27、第3液室28、および第4液室29のうち、いずれか2つの液室は、外側取付部材11、内側取付部材12、または仕切部材15に形成された第1制限通路31を通して互いに連通し、残り1つの液室は、外側取付部材11、内側取付部材12、または仕切部材15に形成された第5液室32に連通し、残り1つの液室は周方向に分割され、これらの周方向に分割された各液室と、第5液室32と、が、外側取付部材11、内側取付部材12、または仕切部材15に形成された第2制限通路33を通して各別に互いに連通している。【選択図】図1
