PROBLEM TO BE SOLVED: To provide a magnetic shielding room apparatus capable of being moved to a plurality of points from place to place, and being readily used without receiving an adverse affect by an environmental magnetic field particular to a floor surface of each point. SOLUTION: In a large magnetic shielding room 3 having an internal space surrounded by a high-permeability material, a plurality of members 20 for keeping an isolation distance consist of a non-magnetic material projecting a necessary length for preventing leakage magnetic field, and is provided at a plurality of downside points of a lower member 6 of the magnetic shielding room 3 with being directed to downside. A hollow tire 28 is provided at each lower part of the members 20 for keeping an isolation distance, so that rotational locomotion on a floor surface is possible, respectively.
