ABSTRACT:
A fluid-filled resilient bushing structure having a resilient member interposed between an inner sleeve and an outer sleeve disposed radially outwardly of the inner sleeve. The resilient member has portions in which are formed plural fluid chambers which are filled with an incompressible fluid and held in communication with each other through an orifice. The resilient bushing structure comprises a non-fixed independent radial stop member of a rigid material accommodated in at least one of the plural fluid chambers and movable in this at least one fluid chamber. The radial stop member is abuttable on surfaces defining the at least one fluid chamber, thereby preventing an excessive displacement of the inner and outer sleeves relative to each other in a radial direction thereof.
