PROBLEM TO BE SOLVED: To provide a fluid sealed cylindrical mount device for advantageously increasing the spring ratio of the latter direction to the former direction only by enhancing a static spring characteristic in the mount shaft direction without enhancing the static spring characteristic in the eccentric direction of inner and outer cylinder members while securing an excellent damping characteristic and a dynamic spring characteristic in the fluid sealed cylindrical mount device. SOLUTION: In this fluid sealed cylindrical mount device 10, an auxiliary arm parts 70 connecting the inner cylinder member 12 and the outer cylinder member 14 independently of a rubber elastic body 16 and composed of a material similar to the rubber elastic body 16, are arranged so as to extend in the mount shaft direction and face to a through space by interposing a separating space 72 extending so as to connect these inner and outer cylinder members 12 and 14 between the auxiliary arm parts and the rubber elastic body 16, and the auxiliary arm parts 70 are respectively arranged on the radial directional both sides of the inner cylinder member 12. |
