Description

[Brief explanation of the drawing]

FIG. 1 is a vertical cross-sectional view (-cross-sectional view in FIG. 2) showing a strut-barcussion which is an embodiment of the present invention, and FIG. 2 is a cross-sectional view (-cross-sectional view) in FIG. 1. FIG. 3 is a longitudinal cross-sectional view corresponding to FIG. 1, showing a vulcanized molded product of the first outer wall rubber constituting the strut bending;
FIG. 4 is a longitudinal cross-sectional view showing an integrally vulcanized molded product of the second outer wall rubber constituting the strut bending. Further, FIG. 5 is a longitudinal cross-sectional view corresponding to FIG. 1, showing the installed state of the strut bark cushion. Furthermore, FIG. 6 is a perspective view for explaining the state in which such a strut trunk is attached to a vehicle. 12: Strut bar (shaft member), 14: Vehicle body (mounting member), 16: Strut bar cushion, 18: Inner cylinder metal fitting, 20: Inner hole, 26: First outer wall rubber, 30: Cylindrical metal fitting, 32: Cylinder wall part, 34: Plate wall part, 36: Orifice cylinder body, 38: Circumferential groove, 46

Claims (1)

[Claims for Utility Model Registration] A cushion rubber device that is interposed between a predetermined shaft member and a mounting member and is designed to isolate vibrations mainly input in the axial direction of the shaft member, comprising: an inner cylindrical metal fitting through which the member is inserted; an outer cylindrical metal fitting that is concentrically arranged radially outwardly of the inner cylindrical metal fitting at a predetermined distance apart and fixed to the mounting member; and the inner cylindrical metal fitting. a pair of outer wall rubber elastic bodies that elastically connect the outer tube fitting and the outer cylinder fitting at both ends in the axial direction to form an annular sealed space between the opposing surfaces; A thick annular plate-shaped plate wall extending in the direction perpendicular to the axis from one side of the cylindrical fitting or the outer cylindrical fitting to the other, and a closed space facing from the peripheral edge of the extending end of the plate wall. It is composed of a thin-walled cylindrical wall extending in one axial direction at a predetermined distance from the inner circumferential surface, and partitions the inside of the sealed space in the circumferential direction into a first fluid chamber and a second fluid chamber. a partitioning rubber wall dividing the fluid chamber into two fluid chambers; a predetermined incompressible fluid sealed in the first fluid chamber and the second fluid chamber; and the first fluid chamber and the second fluid chamber. 1. A fluid-filled cushion rubber device comprising: an orifice passage for communicating with each other;
