Claims

[Claims for Utility Model Registration] An inner cylinder fitting and a metal sleeve arranged at a predetermined distance in the radial direction are integrally connected by a rubber elastic body interposed between them. forming pocket portions that penetrate the metal sleeve and open to the outer circumferential surface on both sides of the body that sandwich the inner cylindrical metal fitting in the radial direction, and insert the outer cylindrical metal fitting into the metal sleeve, By closing these pockets, a predetermined incompressible fluid is sealed to form a plurality of fluid chambers in which relative internal pressure fluctuations are generated when vibration is input, and furthermore, these fluid chambers are communicated with each other. In a fluid-filled cylindrical mount device provided with an orifice passage, a mounting portion for attaching the outer cylindrical fitting to a connected object to be vibration-proofly connected with the cylindrical mount device is attached to the outer cylindrical fitting. In addition to being integrally provided, inner flanges extending radially inward and positioned on the axial end surfaces of the metal sleeve are bent at both axial ends of the outer cylindrical fitting, while A sealing rubber layer with a thickness of at least 1.0 mm is integrally provided on the outer circumferential surface and is pressed between the outer cylinder fitting and the sealing rubber layer is further provided with a layer spanning between the windows in the metal sleeve. forming a concave groove extending in the circumferential direction,
A fluid-filled cylindrical mount device, characterized in that the orifice passage is formed by closing the groove with an outer cylindrical metal fitting.
