ABSTRACT:
A fluid-filled vibration damping bushing including an inner tubular metal member and an outer peripheral sleeve elastically connected via a base rubber interposed therebetween with first and second fluid chambers formed therein. A stopper rubber constituted as a separate element from the base rubber, disposed at a circumferential location corresponding at a minimum to either the first or second fluid chamber, for restricting relative displacement of the inner tubular metal member and outer tubular metal member in an axis-perpendicular direction. The stopper rubber is formed separately from an orifice member and bonded to one axial end portion of the outer tubular metal member at a location outside the first and second fluid chambers so as to face toward the inner tubular member. The outer tubular metal member with the stopper rubber attached thereto is inserted onto the outer peripheral sleeve from the other axial end thereof.
