ABSTRACT:
A cylindrical fluid-filled vibration-damping device including a rubber elastic body elastically connecting an inner and intermediate cylindrical sleeve having an opening portion defined by ring portions and a connecting portion, and an outer cylindrical sleeve disposed on the intermediate sleeve, thereby forming a primary fluid chamber filled with a fluid inside an recessed portion of the rubber elastic body, an auxiliary fluid chamber filled with the fluid and defined by a diaphragm portion and an orifice passage connecting the primary fluid chamber and auxiliary fluid chamber between itself and the connecting portion. A stopper member disposed on the inner cylindrical sleeve and protruding radially in one direction towards the opening portion of the intermediate cylindrical sleeve, and an elastic body striking portion formed of self-lubricating rubber and having a low coefficient of friction and disposed on an inner circumferential surface side of the outer cylindrical sleeve to be opposite to a tip of the stopper member.
