In FIG. 3, permanent magnets 2 are arranged on the stator 1 along the traveling direction. The mover 3 travels on the stator 1, and a superconducting material 4 is provided below the mover 3 so as to face the permanent magnet 2. The superconducting material 4 has a Meissner effect and a pinning effect. The Meissner effect refers to complete diamagnetism of the superconducting material 4. Since the superconducting material 4 has a property of preventing an external magnetic field from penetrating, the magnetic field repels regardless of whether it is the N pole or the S pole. The pinning effect refers to a force that fixes the magnetic flux that has entered the superconducting material 4 so as not to move.
