PURPOSE: To provide a piping supporting structure capable of allowing the displacement of the pipings due to thermal deformation.

CONSTITUTION: Pipe side electromagnets 18,19 are provided on each side of a pipe body 1 in the radial direction with the pole end surfaces facing outward, and fixed side electromagnets 25 provided with pole end surfaces 25a, 25b having the same polarity as those of the respective pole end surfaces 18a, 19a of the pipe side electromagnets 18, 19 are arranged by keeping the prescribed space therebetween so as to be opposite to the respective pole end surfaces 18a, 19a of the pipe side electromagnets 18, 19 where the respective pole end surfaces 2 5a, 25b of the fixed side electromagnets 25 have the same polarity. This constitution allows the opposite pole end surfaces 18a and 25a, and 19a and 25b to be repulsive to each other respectively, and as a result, the pipe body 1 is restricted approximately at the center of the fixed side electromagnets 25.
