Abstract
A fluid-filled vibration damping device including an inner member, an outer member having a tubular part, a main rubber elastic body elastically connecting the two members, and a partition disposed on a radially inner side of the tubular part. An axial end portion of the main rubber elastic body is anchored to a radially inner surface of the tubular part and includes a sealing rubber. The partition includes a press-sealing face positioned at an outer peripheral edge of an axial end face thereof, and is pressed against an axial end face of the sealing rubber at the press-sealing face. A seal rib protruding axially outward from the press-sealing face of the partition is more strongly pressed against the axial end face of the sealing rubber such that a fluid-tight sealing is provided axially between the sealing rubber and the partition.
