Abstract
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.
