PURPOSE: To improve an installing operation property without causing the leakage of liquid by installing a pair of annular rubber elastic bodies to an inner cylinder fitting in a length that generates a compression force, ensuring the air tightness of fluid with respect to a partition member in an installed condition, and externally fitting a cylindrical bracket to an outside sleeve.
CONSTITUTION: A bulkhead rubber 20 is formed with a thin cylinder part 22 which is firmly attached to the whole outer periphery of an inner cylinder fitting 18 and a bulkhead part 24 which is integrally projected outward in the radial direction in the center part in the axial direction. Also, a first orifice forming fitting 28 is joined by vulcanization to the outer periphery of the bulkhead part 24 and a second orifice forming fitting 34 is superposed to it form a partition fitting. Further, a pair of integral vulcanized moldings 46 in which installing fittings 52, outside sleeves 54, and peripheral wall rubbers 56 are integrally formed are installed to the inner cylinder fitting 18 while giving a compression force in the axial direction and forming a liquid housing space 48, and these are fixed by the externally fitting rolled caulking of a bracket 60. Hence, an installing operation property can be improved without causing the leakage of liquid.
