ことを特徴とする流体封入式筒型マウント。[Claims for Utility Model Registration] A rubber elastic body is interposed between an inner cylindrical metal fitting and an outer cylindrical metal fitting that are arranged concentrically or eccentrically to each other, so that the inner cylindrical metal fitting and the outer cylindrical metal fitting are made elastic. In a fluid-filled cylindrical mount having a fluid-sealing portion in which a predetermined incompressible fluid is sealed between the inner and outer cylindrical fittings, , a restraining member is disposed at a predetermined distance from the outer cylindrical metal fitting, and a part of the restraining member is in direct or indirect contact with the outer cylindrical metal fitting to restrict relative displacement; , a restrained part made of a rubber elastic material is provided between the restraining member and the outer cylindrical fitting, and a fluid passes through the outer cylindrical fitting, the restrained part and the restraining member and communicates with the fluid sealing part. While providing an injection hole, an intermediate portion of the fluid injection hole in the constrained portion,
A fluid-filled cylindrical mount characterized in that a spherical enlarged portion is provided, and a fluid injection hole is closed by a sealing sphere fitted into the enlarged portion.
