PROBLEM TO BE SOLVED: To provide a compact fluid sealing type vibration isolating device made by a small number of component items and a simple structure. SOLUTION: By fixing an annular fixing fitting 94 vulcanization adhered to an outer peripheral edge of a rubber elastic plate 92 on an opening portion side of a partition member 60, an opening portion of the fixing fitting is fluid- tightly covered with the rubber elastic plate. Thereby, a pressure receiving chamber 102 having a wall portion partially made of the main body rubber elastic body, an auxiliary liquid chamber 104 having a wall portion partially made of the rubber elastic plate, and a balancing chamber 106 having a wall portion partially made of a flexible film 52 are formed in a fluid chamber 56. On the partition member, a first fluid flow passage 86 is formed between the pressure receiving chamber and the auxiliary liquid chamber, and a second fluid flow passage 88 is formed between the auxiliary liquid chamber and the balancing chamber. Therefore, a first orifice passage communicating the pressure receiving chamber to the auxiliary liquid chamber is formed by cooperating the first and second fluid flow passages connected in series, and a second orifice passage communicating the pressure receiving chamber to the auxiliary liquid chamber is formed by the first fluid flow passage. |
