PURPOSE: To realize both miniaturization and large output of a vibration isolation supporting device which can generate active supporting force by positively changing capacity in a fluid chamber sectioned by a supporting elastic body. CONSTITUTION: A slant surface 4b which is formed in continuity to an upper end part 4a and whose inside is downwardly inclined is formed to an inner cylinder 4, and a supporting elastic body 3 is connected to the inner circumferential surface side of the slant surface 4b. The lower end part of the slant surface 4b turns round the outside diametrically so as to be curved toward a horizontal direction, and the cross section of the side surface of the inner cylinder 4 is formed in V-shaped so as to form a small diametral part 4c. A main fluid chamber 18 is arranged on the inner side of the inner cylinder 4, and also an orifice 16 and an auxiliary fluid chamber 19 are arranged outside the inner cylinder 4. |
