摘要： A fluid-filled vibration-damping device including first and second mounting members elastically connected by a main rubber elastic body and a fluid chamber whose wall is partially constituted by the main rubber elastic body. A sealing member attached to the second mounting member has a step part, and an attaching tube part and a sealing tube part on opposite sides of the step part. A press-fit projection is formed peripherally partially on at least one of an inner peripheral face of the attaching tube part and an outer peripheral face of the second mounting member, so as to secure press-fit the second mounting member inserted into the attaching tube part. A transmission prevention part is provided in the step part on a portion that transmits press-fit stress from the attaching tube part to the sealing tube part so as to reduce stress transmission.

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.
