Abstract
A fluid-filled vibration damping device including an inner member, an outer member having a tubular part whose radially inner surface has a quadrangular tube shape, a main rubber elastic body elastically connecting the two members, and a partition having a quadrangular plate shape disposed on a radially inner side of the tubular part. An outer peripheral surface of an axial end of the main rubber elastic body is anchored to the radially inner surface of the tubular part. An annular sealing rubber pressed against an outer peripheral edge of an axial end face of the partition is provided to the axial end of the main rubber elastic body. An axis-perpendicular inside dimension and a width dimension of the sealing rubber are made larger in a diagonal direction of the radially inner surface of the tubular part than in an opposite side direction thereof.
