FLUID-FILLED VIBRATION-PROOF DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/008836
Kind Code:
A1
Abstract:
Provided is a fluid-filled vibration-proof device which has a novel structure and with which a partitioning member can be stably positioned with respect to an outer member in the axial direction, and superior vibration-proof performance can be achieved. According to this fluid-filled vibration-proof device 10, an inner peripheral surface of a cylindrical part 22 of the outer member 14 has a rectangular cylinder shape, the partitioning member 35 formed in a rectangular plate shape to correspond to the inner peripheral surface 24 of the cylindrical part 22 is arranged on the inner peripheral side of the cylindrical part 22, and the outer peripheral surface of an axial end part of a main rubber elastic body 16 is fixed to the inner peripheral surface 24 of the cylindrical part 22. While an annular seal rubber part 29 pressed against the outer peripheral edge part of the axial end surface of the partitioning member 35 is provided on an axial end part of the main rubber elastic body 16, the internal dimension of the seal rubber part 29 in the direction perpendicular to the axis is formed to be greater in the diagonal direction than in the opposite side direction of the inner peripheral surface 24 of the cylindrical part 22, and the width dimension of the seal rubber part 29 is greater in the diagonal direction than in the opposite side direction of the inner peripheral surface 24 of the cylindrical part 22.
