Document Type and Number:
Japanese Patent JP2019015358
Kind Code:
A
Abstract:
To provide a fluid-sealed vibration control device of a new structure, capable of achieving high fluid sealability between a main body elastic body and a partitioning member axially pressed against each other.SOLUTION: In a fluid-sealed vibration control device 10, an axial end portion of a main body rubber elastic body 16 is fastened to an inner peripheral face of a cylindrical portion 22 of an outer member 14, the axial end portion of the main body rubber elastic body 16 includes a seal rubber portion 30, a partitioning member 32 disposed at an inner peripheral side of the cylindrical portion 22 of the outer member 14 is pressed against an axial end face of the seal rubber portion 30 on a pressing seal face 56 positioned at an outer peripheral edge portion of the axial end face, and a seal projection 54 of the partitioning member 32 projected outward in an axial direction on the pressing seal face 56 is more strongly pressed against the axial end face of the seal rubber portion 30, so that the seal rubber portion 30 and the partitioning member 32 are fluid-sealed in the axial direction.SELECTED DRAWING: Figure 1
