PROBLEM TO BE SOLVED: To provide a noncontact floating transport device for reducing a loss in gas, by simplifying a structure of a carrying device. SOLUTION: By arranging a position of an inflow hole 10 for making the gas flow in a cylinder chamber 19 in an upper position of a central position of a spherical valve element 18 when closing the valve, inclined jetting of the gas in the carrying axis direction increases atmospheric pressure of clearance formed of an upper surface of a carrying base 1 and a flat bottom surface of flat panels 9, and acts so as to carry in the carrying axis direction by floating the flat panels 9 by generating an air current film. While, an air current turning in the cylinder chamber 19 direction by branching off in an edge part of a gas jetting hole 11 detains the spherical valve element 18 in a floating state in an intermediate part in the cylinder chamber 19 by applying wind pressure to the spherical valve element 18. Since a compressed gas flow flowing in the cylinder chamber 19 from an auxiliary hole 16 operates so as to relieve a turbulence state generated in a bottom part of the cylinder chamber 19, the spherical valve element 18 detained in the intermediate part of the cylinder chamber 19 is restrained from the violent vertical movement.
