PROBLEM TO BE SOLVED: To simplify the configuration of a levitation conveyance system 1, while reducing its manufacturing cost. SOLUTION: A plurality of levitation units 41, making a thin plate W levitate are provided to the unit body 29 of a changeover apparatus so as to be surrounded by a plurality of receiving rollers 31 and a plurality of delivery rollers 35. Among all the levitation units 41, a levitation unit 41T adjacent to the receiving rollers 31 and a levitation unit 41G adjacent to the delivery rollers 35 are configured so as to be switchable independently between a normal levitation power state exercising a normal levitation power and a low levitation power state that exercise lower levitation power than the normal levitation power, respectively.
