PROBLEM TO BE SOLVED: To provide a seat site movement supporting apparatus capable of dealing with a low bed or a stretcher without positional deviation of a boarding part even when a moving mechanism is turned with respect to a body having the boarding part. SOLUTION: The seat site movement supporting apparatus comprises a first motor 20 for rotating the moving mechanism turning with respect to the body having the boarding part to turn the mechanism to the body by a worm gear 34 with a turning shaft as an output of the gear, a pair of drive wheels 3L, 3R mounted by matching rotary shafts to each other to the same axes, and second and third motors 19L, 19R for rotating the pair of the drive wheels, respectively. In this apparatus, a rotating shaft 36 of the mechanism 6 is a substantially a mid-point of a line for connecting the rotating centers of the pair of the wheels, and the gear 34 and the first motor 20 are disposed between the pair of the wheels.
