PURPOSE:To reduce magnetic flux leaking out of a transportation track for a vehicle levitated by pinning effect of a high-temperature superconductor, by covering a magnetic-field generating means almost entirely with a magnetic shielding unit. CONSTITUTION:A transportation track 3, where a vehicle 10 is levitated and moved, comprises a permanent magnet 5 for generating a given pattern of a magnetic field, and magnetic shielding units 4a and 4b made of ferromagnetic material like an iron for enclosing the permanent magnet 5. A plurality of permanent magnets 5 are laid all along the track 3 to form a given pattern of magnetic field across the transportation track 3. Through a notched part 23 of the magnetic shielding units 4a and 4b, the vehicle 10 made up of a mounting member 20, a container 22, and a high-temperature superconductor 21 can be moved freely on the track 3. Then, a 1iquid nitrogen is infected in the container 22 to cool the high-temperature superconductor 21. A linear-motor stator 6 for providing thrust to move a vehicle 10 on the track 3 is fixed to a placement member 7 on a base 2. Consequently, strong magnetic flux leaking out of the track 3 can be prevented, and a bad effect caused by the magnetic flux can be prevented.
