PROBLEM TO BE SOLVED: To reduce malfunction due to transmitted vibration by improving structure of a stopper in a liquid sealed type vibration-control support device so as to restrict a rise of a spring interlocked with operation of the liquid sealed type vibration-control support device. SOLUTION: In a liquid sealed type engine mount A used wide for automobiles, a stopper fitting 8 is arranged so as to surround a connecting fitting provided in an engine in an upper part of a support fitting 3 provided in a car body. A stopper portion 7 is provided in the periphery of a flange part 10 of the connecting fitting 1 so as to regulate displacement relative to the support fitting 3 by abutting on the stopper fitting 8. The stopper portion 7 is formed of an annular rubber portion 70 provided in the periphery of the flange part 10 and a metallic cylindrical member 71 covering the periphery of the annular rubber portion 70. The annular rubber portion 70 is formed with liquid chambers 70a and 70b with the flange part 10 between them in the back and forth direction, and the liquid chambers 70a and 70b are connected with each other by an orifice passage 13 passing through the flange part 10 in the radial direction.
