PROBLEM TO BE SOLVED: To improve the performance of sealing an orifice passage in a partition member made of a plurality of members. SOLUTION: A first mounting member 1 and a second mounting member 2 are connected by an elastic body part 3, and an internally delimited liquid chamber is divided by a partition member 15 into a main liquid chamber 17 and a subsidiary liquid chamber 18 that are connected by an idle orifice passage 20 and damping orifice passages 21. The partition member 15 is assembled when an intermediate member 41 of an elastic material such as rubber is placed between an upper member 40 and a lower member 42 having relatively higher rigidity. The partition member 15 defines the idle orifice passage 20 and the two-stage or upper and lower damping orifice passages 21 along the mating faces of the constituent members, and has a peripheral portion fixed to the second mounting member 2. That boundary between the idle orifice passage 20 and the upper damping orifice passage 21 which is inside of the fixed portion is sealed in taper-matching construction where taper portions 41a and 49 are placed in sliding contact in upper-lower relation. |
