Abstract:
1. A magnetic shielding door for opening and closing a gate formed in a wall portion of a magnetic shielding room, the wall portion provided with plural magnetic members made of a magnetic material, the magnetic members being aligned at intervals on a circumference of the gate, the magnetic shielding door comprising: plural magnetic shielding forming members disposed to respectively correspond to the magnetic member and made of a magnetic material that forms a magnetic shielding in cooperation with the magnetic members, the respective magnetic shielding forming members being disposed in a posture extending in a horizontal direction; and a movable mechanism that moves the respective magnetic shielding forming members at a door closing position at which the gate is closed, the magnetic members and the magnetic shielding forming members being parallel to each other at the door closing position, and being configured to join the respective magnetic members and the corresponding magnetic shielding forming members to each other along a longitudinal direction substantially parallel to the wall portion at the door closing position, the movable mechanism being capable of moving the respective magnetic shielding forming members up and down between a join position at which the respective magnetic shielding forming members are on the corresponding magnetic members to be joined with its own weights and a spaced apart position located above the join position at which the magnetic members and the magnetic shielding forming members are spaced apart from each other in the longitudinal direction.
