Claims

[Claims for Utility Model Registration] An inner cylindrical metal fitting and an outer cylindrical metal fitting are elastically connected by a cylindrical rubber elastic body interposed between them, and the inner cylindrical metal fitting inside the rubber elastic body By forming pocket portions opening on the outer circumferential surface at portions located opposite to each other in one radial direction while holding the A compressible fluid is sealed to form a pair of fluid chambers that communicate with each other through an orifice passage, and each of the fluid chambers protrudes at a predetermined height from the inner cylindrical metal fitting side to the outer cylindrical metal fitting side in the integrated fluid chamber. In a fluid-filled anti-vibration bushing in which a stopper member having a stopper portion is externally fitted and fixed to the inner cylindrical metal fitting, both side portions of the stopper member perpendicular to the protruding direction of the stopper portion are made thinner so that the outer circumferential surface thereof becomes thinner. On the one hand, the protruding end surfaces of the stopper parts of the stopper member are each formed in an arc shape approximately corresponding to the inner circumferential surface of the outer cylindrical metal fitting, and on the protruding end surface of the stopper part. The fluid enclosure is characterized in that a stopper rubber layer is integrally provided over substantially the entire surface of the protruding end surface, protruding most outwardly at the circumferential center thereof and having a short opposing distance to the outer cylindrical metal fitting. Anti-vibration bushing.
