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. An axial dimension of each elastic member before being mounted on the inner sleeve is determined to permit each elastic member to be axially compressed upon mounting of the elastic members, so that the outer sleeves are urged against the orifice structure with a force sufficient to maintain fluid tightness between the elastic members and the orifice structure, whereby the mounting of the bracket on the outer sleeves of the elastic members may be effected in a condition that the fluid chambers are filled with the fluid.
