<P>PROBLEM TO BE SOLVED: To exhibit high supporting force correction sensibility for supporting position correction while having a very low spring constant required for vibration isolation performance, and to remarkably suppress a control energy consumption amount in correction control of the supporting force. Ž<P>SOLUTION: A vibration isolation supporting device includes a first spring element 15 arranged between a supporting member 10 and a fixing member 14 and having a relatively high spring constant, a second spring element 16 arranged between the supporting member 10 and a supporting force correction control member 12 and having a spring constant having the inverted relationship in positive/negative with the spring constant of the first spring element 15, a third spring element 17 arranged between the supporting force correction control member 12 and the fixing member 14 and having a spring constant having the inverted relationship in positive/negative with the spring constant of the second spring element 16, a correction thrust generation hydraulic piston/cylinder mechanism 13 receiving the hydraulic pressure and imparting the correction thrust in accordance with the hydraulic pressure to the supporting force correction control member 12, and a hydraulic pressure conversion device 62 for making the output hydraulic pressure in accordance with displacement of the supporting member 10 act on the correction thrust generation hydraulic pressure piston/cylinder mechanism 13.
