PURPOSE:To realize a fluid-seal vibrationproof supporting device having a simple structure and no possibility of leakage of fluid. CONSTITUTION:A bulkhead composed of two rubber elastic bodies axially arranged at distances and a bulkhead 16 composed of a cross-linked rubber elastic body extending between side walls along a flat surface including a shaft 12 are respectively provided between the shaft 12 arranged in a cylindrical case 10 and the case 10, and first and second fluid chambers 20, 22 into which non-compressive fluid is filled are partitively formed on both sides of the bulkhead 16, and a communication passage 28 for fluid is formed. A full round ring 18 wherein communication passages 28, 30 are formed on the outer periphery is arranged along the inner peripheral surface of the case 10 in the first and second fluid chambers, while holes 24, 26 for communicating the communication passages 28, 30 with the first and second fluid chambers are formed, and a control member 34 for adjusting a flow rate of the fluid to flow into and through communication passage 30 is so provided as not to protrude from the case 10. |
