Title:
FLUID-FILLED VIBRATION-DAMPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/008837
Kind Code:
A1
Abstract:
Provided is a fluid-filled vibration-damping device having a novel structure, the vibration-damping device being configured to obtain high fluid-tightness between a body rubber elastic body and a partition member, which are axially pressed against each other. This fluid-filled vibration-damping device 10 is configured so that an axial end of a body rubber elastic body 16 is secured to the inner peripheral surface of the cylindrical section 22 of an outer member 14, the axial end of the body rubber elastic body 16 is provided with a seal rubber section 30, a partition member 32 disposed on the inner peripheral side of the cylindrical section 22 of the outer member 14 is pressed, at a pressing seal surface 56 located at the outer peripheral edge of an axial end surface, against an axial end surface of the seal rubber section 30, the seal ridge 54 of the partition member 32, which protrudes axially outward from the pressing seal surface 56, is pressed stronger against the axial end surface of the seal rubber section 30, and the seal rubber section 30 and the partition member 32 are axially and fluid-tightly sealed relative to each other.
