PROBLEM TO BE SOLVED: To provide a support apparatus for correcting balance of a rotational body, which can stably support and rotate the heavy rotational body even having heavy weight in a floating state, using a fluid. SOLUTION: In the support apparatus of a balance correcting device for measuring imbalance force, a journal support part 22 having a mandrel 21 for supporting a rotational body 11 around the vertical axis is provided; a trust support part 23 for supporting a bottom part 13 of the rotational body 11 is provided at the lower end part of the mandrel 21; a first fluid supply path 27 for supplying the fluid for the floating is provided between the mandrel 21 and a rotational support hole 12 of the rotational body 11, and an annular groove 28 and a second fluid supply path 29 in communication therewith for supplying the fluid for floating the rotational body are provided at the thrust support part 23 disposed opposite the bottom part 13 of the rotational body 11. Accordingly, the fluid flows out from the annular groove 28 so that the inner circumferential side from this is sufficiently filled with the fluid, and the sufficient floating amount is secured for the rotational body 11 even having the heavy weight, and the stable rotation along the mandrel 21 is performed.
