PURPOSE:To easily set the center distance of facing coils to be a specified value, and prevent the generation of internal stress at the time of fixing, by a method wherein, after cure resin is arranged on the periphery of the roots of bolts protruding from a coil fixing track and a coil is preliminarily fixed, the coil is finally fixed after a specified period by using nuts. CONSTITUTION:When coils 6a, 7a, 8a are preliminarily fixed, cure resin 21, 22 has not yet cured, so that the resin is easily deformed by fastening nuts 15, 19. Thereby the distance L1, L2, L3 between the centers of the coils 6a, 7a, 8a and the coil center of a superconducting magnet 2a of a superconducting electromagnetic levitation vehicle can be easily adjusted to be specified values. At this time by fastening the nuts 15, 19, the cure resin 21, 22 is pressed with a pressure by the coils 6a, 7a, 8a, so that the cure resin 21, 22 comes into contact with propulsion coils 6a, 8a so as to ensure an area and forms no gaps. Thereby, when the cure resin 21, 22 is completely cured, the gap between the cure resin 21, 22 and each fixing part of the propulsion coil 6a is kept zero, and high stress is not generated inside the coils 6a, 7a, 8a in the case of final fixing by fastenting the nuts with specified torque. |
