A pair of pocket portions connecting these two metal fittings are formed so as to be opposed to each other in one direction in the radial direction with the inner cylindrical metal fitting in between, each having a peripheral wall surface rising toward the opening side in the opposing direction. The inner and outer cylindrical metal fittings are formed by a cylindrical rubber elastic body and a pair of pocket portions provided on the rubber elastic body, each opening of which is fluid-tightly covered by the outer cylindrical metal fitting. A pair of fluid chambers each having a predetermined incompressible fluid sealed therein causes a relative internal pressure fluctuation when vibration is input between the fluid chambers. an orifice passage that allows fluid to flow between the chambers; and an orifice passageway that has an annular shape and is attached to the inner cylindrical fitting by protruding at a predetermined height into each of the pair of fluid chambers. A pair of stopper parts are opposed to each other at a predetermined distance from the circumferential surface and restrict deformation of the rubber elastic body by abutting against the outer cylindrical metal fitting, and the stopper parts are arranged in a direction substantially perpendicular to the direction in which the stopper parts protrude. a stopper fitting having a support portion provided with an arrangement hole that projects and extends in opposite directions of the pair of fluid chambers; is inserted so as to be displaceable in the penetrating direction to prevent free flow of fluid between the fluid chambers through the arrangement hole, and to substantially prevent fluid flow between the fluid chambers based on the displacement within the arrangement hole. a movable member that allows a fluid to flow; and a movable member that is supported by a stopper portion of the stopper fitting, and is disposed within each of the pair of fluid chambers, and has an outer circumferential surface between the movable member and the peripheral wall surface of the fluid chamber. An annular narrowed portion is formed in the stopper metal fitting, while the inner surface located on the inner cylinder metal fitting side is positioned opposite to the opening of the installation hole provided in the support portion of the stopper metal fitting at a predetermined distance from each other. 1. A fluid-filled cylindrical mount device comprising: a pair of umbrella metal fittings that regulate the amount of displacement of the movable member by abutting the movable member against the inner surface.
