PROBLEM TO BE SOLVED: To make amplitude of vibration small against respective X, Y, and Z axial directions with regard to respective vibrations of three axial directions X, Y, and Z mutually crossing each other. SOLUTION: A main liquid chamber 10 having the inside wall of a dome 6 as a part of an elastic wall is formed by a first fitting member 3, a second fitting member 4, an elastic main body 5, a partition member 8, and a first orifice passage 15, and a conical mount 1 connected to a sub liquid chamber 11 through the first orifice passage 15 is provided. The chief inputting direction of vibration is formed in the Z-direction (vertical direction of car body). A pair of main liquid chambers 20 having the external wall as a part of an elastic wall on the dome 6 are arranged in the X-axis direction and a pair of hollows 27 are arranged respectively in the Y-axis direction. A sub liquid chamber 25 is formed by partitioning the hollow 27 by the diaphragm 28 and the sub liquid chamber communicates with the front side main liquid chamber 20 through a damping orifice passage 24 and communicates with the rear side main liquid chamber 20 through an idle orifice passage 26. |
