FLUID-FILLED VIBRATION DAMPING DEVICE

WIPO Patent Application WO/2016/092917

A1

Provided is a fluid-filled vibration damping device having a novel structure, wherein the fluid-tightness of a fluid chamber can be advantageously obtained by simple mounting. A fluid-filled vibration damping device 10 is configured so that: a cylindrical sealing member 72 is mounted to a second mounting member 18; the sealing member 72 has a mounting cylinder section 80 and a seal cylinder section 74, which are respectively provided on both sides of a stepped section 78; the inner peripheral surface of the mounting cylinder section 80 and/or the outer peripheral surface of the second mounting member 18 has a press-in protrusion 82 partially circumferentially formed thereon; the second mounting member 18 is inserted in the mounting cylinder section 80 and affixed by press-fitting at the portion where the press-in protrusion 82 is formed; and a transmission prevention section 84 is provided to the stress transmission portion of the stepped section 78 of the sealing member 72, the transmission prevention section 84 reducing the transmission of stress from the mounting cylinder section 80 to the seal cylinder section 74, the stress being caused by the press-fitting.
