Abstract: A fluid-filled cushioning device having a cylindrical elastic body mounted on an inner sleeve and having an orifice structure with an orifice formed therethrough is disclosed. A pair of annular elastic members each having a retainer member and an outer sleeve are mounted on the inner sleeve such that the retainer member is press-fitted in the axial end portion of the inner sleeve while the orifice structure is sandwiched between the axial end faces of the outer sleeves, in the axial direction. A bracket is mounted on the outer sleeves of the elastic members and is fixed to a support member, so that the bracket forces the outer sleeves against the orifice structure. The inner sleeve, elastic body and elastic members define two fluid-filled chambers which are separated from each other by the elastic body and which communicate with each other through the orifice.
