PURPOSE:To eliminate the resonance of a superconducting magnet due to a magnetic force on a traveling magnetic levitation train and prevent heat generation in the superconducting magnet by providing a case for the superconducting magnet with a damper having one end fixed and the other end pressed against the case. CONSTITUTION:A superconducting magnet 2 is mounted on the chassis 5 of a magnetic levitation train. The superconducting magnet comprises a superconducting magnet body 6, a shield plate 7 for protection from external heat, a case 8 for enclosing the superconducting magnet body, and a support 9 for carrying the superconducting magnet. The case 8 is fitted with a damper 10, which includes a base 11 fixed to the inner surface of the case 8, and a damper plate 13 that has one end in contact with the inner surface of the case and the other end bolted or welded to a slope of the upper surface of the base 11. Since the damper plate 13 is inclined with respect to the inner surface of the case, its one end is pressed against the inner surface of the case. |
