Beschreibung
Zusammenfassung:	A fluid-filled elastic bushing including an inner sleeve and an outer sleeve disposed radially outwardly of the inner sleeve, an elastic member elastically connecting the inner and outer sleeves, so as to provide an assembly having a plurality of fluid-filled chambers which are spaced apart from each other in a circumferential direction of the sleeves and an orifice for fluid communication between the chambers, and a wing member disposed in at least one pressure-receiving chamber of the fluid chambers to which a vibrational load is applied. The wing member is supported by one of the sleeves and the elastic member, and cooperates with the assembly to define a restricted portion within the pressure-receiving chamber. A restrictor member is fixedly disposed so as to extend in the elastic member in an axial direction of the elastic bushing, for limiting axial elastic deformation of axial end portions of the elastic member which define opposite ends of the pressure-receiving chamber as viewed in the axial direction of the elastic bushing.
