摘要： A fluid-filled tubular vibration-damping device including: an inner shaft member; an intermediate tube member spaced radially outward therefrom; a main rubber elastic body connecting the two members; an outer tube member fastened externally onto the intermediate tube member; a pair of fluid chambers formed between the inner shaft member and the outer tube member so as to be on opposite sides of the inner shaft member; and an orifice passage interconnecting the fluid chambers. In at least one of the fluid chambers, at least one of side walls positioned on axially opposite sides includes a thick central connector positioned in a circumferentially central portion of the side wall and extending in an axis-perpendicular direction, and thin flexible walls that are thinner than the central connector while being positioned and spreading on circumferentially opposite sides of the side wall.

摘要： A fluid-filled vibration damping device including a vibration damping device main unit which has a main rubber elastic body elastically connecting first and second mounting members, and a fluid chamber whose wall is partially constituted by the main rubber elastic body. The vibration damping device main unit further includes a temporary joint member locked on the second mounting member and temporarily coupled thereto in an axial direction, and an annular sealing part provided to the temporary joint member and overlapped on the second mounting member in the axial direction with a sealing rubber sandwiched therebetween for achieving a temporary seal. A sealing coupling member is mounted on the second mounting member while exerting a pressing force in a direction of overlapping on the second mounting member and the temporary joint member for increasing a compression ratio of the sealing rubber and achieving a full seal.
