To improve a magnet core protecting shoe device of modules of a normal conducting attraction magnetic levitation type vehicle.
Modules 20 on right and left which are equivalent to bogies each includes a magnetic coil, and magnetically attract rails to levitate the vehicle. The magnet core protecting shoe device whose entire part is shown by a symbol 700 is arranged adjacently to magnet coils 250. The magnet core protecting shoe device 700 protects a magnet core 220 when the magnet coils 250 contact a rail due to an abnormally increasing an attractive force of each of the magnetic coils. This protecting shoe 720 is inserted into an attaching portion 710 from a side surface of the magnetic core 220, and fixed with screws 740 while pressing both sides by a side plate 730. An upper surface 722 of the protecting shoe 720 protrudes upward from the upper surface 222 of the magnet core 220, and even when the magnet coils 250 are adsorbed to the rail due to abnormal absorption, the protecting shoe 720 abuts on the rail, thereby protecting the magnet core 220.
