PROBLEM TO BE SOLVED: To prevent an outer tank from being damaged by foreign matters which come into contact with the outer tank and a tank, while a vehicle is running. SOLUTION: On the surface of an outer tank 7, a coating film 22 is formed of polyurethane paint containing ceramic particles. Since a breakage preventing section is formed on at least either one of the tank 7 and a tank 19, foreign matters are attracted by strong magnetic field formed by a superconducting coil and the attracted foreign matters collide with the tanks 7 and 19 while a vehicle is running at a superhigh speed, but the damages to the tanks 7 and 19 are reduced by the breakage preventing section. |
