PURPOSE:To provide a superconducting magnet levitation device of which a thickness of a movable part can be thinned and in which an invasion of heat can extremely be suppressed. CONSTITUTION:A movable part 30 comprises a double structure having an outer wall 8 and an inner wall 9 and a multiple spacer 11 is arranged in a hollow part. A high temperature superconductor 5 is received inside the movable part 30 and also refrigerant is sealed therein. The movable part 30 is magnet- levitated by a permanent magnet 2 arranged on a rail 1 and a high temperature superconductor 5. |
