description	PROBLEM TO BE SOLVED: To provide a novel fluid-sealed vibration isolating device with a simple structure capable of accurately setting the pressure of an air chamber formed at the opposite side of an equilibrium chamber with a flexible film between. SOLUTION: A cover member 44 is provided for covering the rear of the flexible film 40 to form the air chamber 56 at the opposite side of the equilibrium chamber 52 with the flexible film 40 between, and a pressurization hole 58 is formed piercing the cover member 44. A rubber elastic plate 60 covering an inner side opening of the pressurization hole 58 is overlapped on the inner face of the cover member 44, and the rubber elastic plate 60 is partially bonded to the cover member 44. An nonbonded area 64 from the pressurization hole 58 toward the air chamber 56 is formed between overlapping faces of the rubber elastic plate 60 and the cover member 44, and the rubber elastic plate 60 is pressed against the overlapping face of the cover member 44 by the pressure of compressed air injected into the air chamber 56 from the outside through the nonbonded area 64 from the pressurization hole 58. By this, the compressed air is sealed in the air chamber 56. COPYRIGHT: (C)2007,JPO&INPIT
