To provide a vehicular vibration isolating device capable of sufficiently attenuating vibrations in a wide frequency zone.SOLUTION: A vehicular vibration isolating device 1 is equipped with a first attaching member 5 to be attached to a first member 2, a second attaching member 6 to be attached to a second member 3, a first liquid chamber 10 and a second liquid chamber 11 that change capacities according to the relative displacement of the first attaching member 5 and the second attaching member 6, and an orifice passage 12 circulating liquid M between the first liquid chamber 10 and the second liquid chamber 11 according to the change of the capacities of the first liquid chamber 10 and the second liquid chamber 11. The liquid M includes a non-Newtonian fluid whose viscosity lowers according to a rise of shear velocity. Particles P having different density from the non-Newtonian fluid are added to the liquid M.SELECTED DRAWING: Figure 1

    【課題】 広い周波数領域において振動を十分に減衰させる車両用防振装置を提供する。【解決手段】 車両用防振装置1であって、第1部材2に取り付けられる第1取付部材5と、第2部材3に取り付けられる第2取付部材6と、第1取付部材5と第2取付部材6の相対変位に応じて容積を変化させる第1液室10及び第2液室11と、第1液室10と第2液室11の容積の変化に応じて第1液室10と第2液室11の間で液体Mを流通させるオリフィス通路12とを備え、液体Mが、せん断速度の上昇に応じて粘度が低下する非ニュートン流体を含み、液体Mには、非ニュートン流体とは密度の異なる粒子Pが添加されている。【選択図】 図1
