FLUID-FILLED VIBRATION DAMPING DEVICE AND METHOD OF MANUFACTURING THE SAME

摘要

A fluid-filled vibration damping device including: first and second mounting members elastically connected by a main rubber elastic body; a tubular fitting member externally slipped around the second mounting member and drawn so as to be externally fitted thereto in a fluid-tight manner; a sealing rubber layer fixed to at least one of an outer peripheral face of the second mounting member and an inner peripheral face of the tubular fitting member so as to be compressed therebetween about an entire circumference; and at least one pressure-relieving lip protruding from the sealing rubber layer and extending toward openings of the second mounting member and the tubular fitting member so as to be pressed against one of the outer peripheral face of the second mounting member and the inner peripheral face of the tubular fitting member in a direction of protrusion.

1. A fluid-filled vibration damping device comprising:
a first mounting member; a tubular second mounting member; a main rubber elastic body elastically connecting the first and second mounting members; a tubular fitting member externally slipped around the second mounting member that is fixed to an outer peripheral face of the main rubber elastic body, the tubular fitting member being drawn and externally fitted onto the second mounting member in a fluid-tight manner so as to provide a fluid chamber whose wall is partially constituted by the main rubber elastic body and which is filled with a non-compressible fluid; a sealing rubber layer fixed to at least one of an outer peripheral face of the second mounting member and an inner peripheral face of the tubular fitting member so as to be compressed between the second mounting member and the tubular fitting member about an entire circumference; and at least one pressure-relieving lip protruding from the sealing rubber layer and extending toward openings of the second mounting member and the tubular fitting member so as to be pressed against one of the outer peripheral face of the second mounting member and the inner peripheral face of the tubular fitting member in a direction of protrusion.
