To raise a vibration resistant stand up to target displacement from a sitting position while maintaining levelness of the vibration resistant stand even when mounting a structure having the high center of gravity.
A control command Pr is imparted to at least three actuators 11, 12, 13, and a vibration resistant stand 1 is raised up to a first height position slightly higher than a sitting height position (a floating process 1: Step 106, 107). Next, the fact that respective displacements (z) of at least the three actuators 11, 12, 13 become the same displacement is confirmed (a floating process: Step 108). Next, the control command Pr for gradually raising the displacements (z) of at least the three actuators 11, 12, 13 is imparted to the actuators so that the vibration resistant stand 1 is made to gradually reach up to the final target height position (zs) from the first height position (a floating process 2: Step 109, 110, 111).
