PROBLEM TO BE SOLVED: To provide structure capable of effectively tuning a static spring characteristic of a rubber elastic body while effective vibration insulated effect based on fluidic action of fluid between fluid chambers is secured in fluid encased type vibration insulated mount which performs vibration insulation for bidirectional input vibration intersecting with combination of the two distinct fluid chambers. SOLUTION: The fluid encased type vibration insulated mount is constituted so that a plurality of the fluid chambers 48 within which incompressible fluid are encased in the rubber elastic body 16 are provided to position around a shaft part 20 of first mounting metallic ornament 12, a plurality of the fluid chambers 48 enable to be communicated with each other at second orifice passage 50 and the incompressible fluid can flow between the fluid chambers 48, 48 and at the same time, in axial direction of the shaft part 20 of the first mounting metallic ornament 12, it is constituted as a thin walled part that is easy to elastically deform so that an inside wall part 52, which is situated between the fluid chamber 48 and a received pressure chamber 44 and which is provided by the rubber elastic body 16, enable to be walled thinner than an outside wall part 54 which is provided by the rubber elastic body 16. |
