PROBLEM TO BE SOLVED: To provide the packing structure of a superconductive device which is capable of lowering the probability of damage of the superconductive device due to impact and steady oscillation, while capable of preventing increase in cost.SOLUTION: The packing structure of a superconductive device has: a box body 3 for storing the superconductive device 2 inside; a shock absorbing material 5 supporting the lower surface of the box body 3, and installed on a transportation platform 4 when transporting the superconductive device 2; and a vibration absorbing material 6 supporting the superconductive device 2, and disposed between the box body 3 and the superconductive device 2. The natural vibration frequency of a system made of the box body 3 including the vibration absorbing material 6 and superconductivity device 2 and of the shock absorbing material 5 includes the setting of the length of time required for the potential energy of the system at a prescribed height from the transportation platform 4 to act upon the system, at a value equal to or higher than a predetermined value. The natural vibration frequency of a system made of the vibration absorbing material 6 and the superconductive device 2 is set at a value smaller by a differential of 1/√2 than the lowest value of the vibration frequency during transportation. |
