To provide a vehicular vibration isolating device capable of sufficiently attenuating vibrations in a wide frequency zone.SOLUTION: A vehicular vibration isolating device is equipped with a first attaching member to be attached to a first member, a second attaching member to be attached to a second member, a first liquid chamber 10 and a second liquid chamber 11 that change capacities according to the relative displacement of the first attaching member and the second attaching member, and an orifice passage 12 circulating liquid 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 includes a non-Newtonian fluid whose viscosity lowers according to a rise of shear velocity. The orifice passage 12 includes a main passage part 31 connecting the first liquid chamber 10 and the second liquid chamber 11, and a sub passage part 32 merging with the main passage part 31.SELECTED DRAWING: Figure 3

    【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】 車両用防振装置であって、第1部材に取り付けられる第1取付部材と、第2部材に取り付けられる第2取付部材と、第1取付部材と第2取付部材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の間で液体を流通させるオリフィス通路12とを備え、液体が、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、オリフィス通路12が、第1液室10と第2液室11とを互いに連通する主通路部分31と、主通路部分31に合流する副通路部分32とを含む。【選択図】 図3
