PROBLEM TO BE SOLVED: To provide a vibration control supporting device which can stabilize the vibration control performance by enlarging the volume of a sub-fluid chamber while miniaturizing and also provided with the heat radiation function of an enclosed fluid. SOLUTION: The portion between oneside of a vibration body side or support body side and a support elastic body is combined with a cylindrical storing body so that the axial center can be pointed to the vibration body support direction and a main fluid chamber, movable member and actuator are arranged inside the storing body. A sub-fluid chamber 40 and orifice passage 38 are arranged outside the storing body. The orifice passage formed by a fluid pipe is connected between the main fluid chamber and sub-fluid chamber. Here, the sub-fluid chamber is formed as a fluid chamber, partitioned the inside space of a fluid case 20B to two chambers by a diaphragm 46 consisting of a film shape elastic body, for enclosing the fluid by communicating oneside of these chambers with a fluid pipe and whose volume is varied by the expansion direction spring of the diaphragm. |
