Abstract

A fluid filled type cylindrical vibration damping device, wherein a circumferential end of a stopper member is formed as a mating element smaller in diameter than a circumferentially center section of the stopper member, and is juxtaposed against and supported on a bottom face of a mating groove in a communication passage, to form the communication passage along an entire area between diametrically opposed faces of the mating element and an outer tubular member. A cutout portion is formed extending in a circumferential direction from a circumferential end in a widthwise medial section of the mating element, with the communication passage opening into and communicating with a first fluid chamber at a distal end section of the cutout portion, and at two widthwise side sections of the mating element, respectively, thereby defining an orifice passage connecting the first fluid chamber with a second fluid chamber.
