PURPOSE:To obtain the simple structure, which can be easily manufactured without performing restriction and caulking in the liquid. CONSTITUTION:A rubber elastic body 16, which has the nearly conical trapezoidal shape and to which a first fitting 12 is fixed at the small diameter side end, is formed with a cylindrical projecting part 28, which is projected in the axial direction from the large diameter side end and which has the hook-like cross section. This cylindrical projecting part 28 is fitted for fixation in a fitting part 40 of a second fitting 14, and a fluid escape passage 42, which is sealed by fitting, is provided in a fitting part of the cylindrical projecting part 28 and the fitting part 40. |
