Magnetic shielding door and magnetic shielding room

A magnetic shielding door opens and closes a gate of a magnetic shielding room. Magnetic members made of a magnetic material are aligned at intervals on walls of the magnetic shielding room. Magnetic shielding forming members are disposed to correspond to the respective magnetic members and are made of a magnetic body that forms a magnetic shielding in corporation with the magnetic members. A movable mechanism moves the magnetic shielding forming members at the door closing position at which the gate is closed. The movable mechanism moves the magnetic shielding forming members between a join position at which the magnetic members and the corresponding magnetic shielding forming members are joined to each other and a spaced-apart position at which the magnetic members and the corresponding magnetic shielding forming members are spaced apart.
