Document Type and Number:
Japanese Patent JP2019015359
Kind Code:
A
Abstract:
To provide a fluid-sealed vibration control device of a new structure capable of stably axially positioning a partitioning member with respect to an outer member, and realizing excellent vibration control performance.SOLUTION: In a fluid-sealed vibration control device 10, an inner peripheral face of a cylindrical portion 22 of an outer member 14 is formed into the shape of square cylinder, a partitioning member 35 formed into the shape of square plate corresponding to the inner peripheral face of the cylindrical portion 22 is disposed at an inner peripheral side of the cylindrical portion 22, an outer peripheral face of an axial end portion of a main body rubber elastic body 16 is fastened to the inner peripheral face of the cylindrical portion 22, the axial end portion of the main body rubber elastic body 16 is provided with an annular seal rubber portion 29 pressed against an outer peripheral edge portion of an axial end face of the partitioning member 35 on one hand, an inner dimension in an axially perpendicular direction of the seal rubber portion 29 is larger than an opposite side direction in a diagonal direction of the inner peripheral face of the cylindrical portion 22, and a width dimension of the seal rubber portion 29 is larger than the opposite side direction in the diagonal direction of the inner peripheral face of the cylindrical portion 22.SELECTED DRAWING: Figure 1
