PROBLEM TO BE SOLVED: To provide a liquid-sealed vibration insulator which is simple in structure, easy to manufacture, and capable of obtaining reliable rust preventing effect. SOLUTION: A cylindrical side plate 4 is joined to the outer periphery of a vibrationproof rubber body 1 formed into a container shape, of a liquid sealed vibration isolator sectioned into a main liquid chamber a taking A thick vibrationproof rubber body 1 as a camber wall and a sub liquid chamber B taking a thin rubber film 2 as a chamber wall by a partition plate 3 on which a throttle passage F is formed, and it is fixed in a cylindrical holder 5 provided on a vehicular frame, and an engine is supported by a connecting member 11 buried in the bottom part. A ring plate 21 joined to the outer peripheral edge of the partition plate 3 and the outer periphery of the rubber film 2 is overlapped on and caulked to the upper opening edge of the side plate 4 exposed from the holder 5, and the front surface of the side plate 4 positioned on the outer peripheral side of the caulking part is covered with a thin rubber film 12 having the high rust preventing effect. The rubber film 12 can be integrally provided on the vibrationproof rubber body 1, and the rust preventing effect can be easily obtained. |
