[Claims for Utility Model Registration] a. a cylindrical rubber elastic body equipped with a pair of pocket portions located on opposite sides of the axis and opening on the outer circumferential surface; a pair of fluid chambers in which a predetermined incompressible fluid is sealed, each of which is fluid-tightly closed by a cylindrical member; an orifice that allows a predetermined incompressible fluid sealed in the fluid chambers to mutually flow; a stopper member of a predetermined height, which is provided in a state in which the stopper member extends toward the bushing axis, and a side face in the bush axis direction faces the inner wall surface in the axis direction of the fluid chamber at a predetermined distance; g A fluid-filled vibration damping device including, at the distal end portion of the stopper member, a flange portion that protrudes by a predetermined distance from the stopper member toward the inner wall surface around the pocket portion where the stopper member is located. In the bush, a pocket portion of a rubber elastic body constituting at least one of the pair of fluid chambers in which the stopper member is provided is formed with an inner wall surface extending in a direction perpendicular to the bush axis corresponding to the vibration input direction. At least, when vibration is input, the flange portion provided on the stopper member is relatively moved along the inner wall surface of the fluid chamber. .
