Abstract

A magnetically shielded room, that is capable of suppressing positional deviation of a measuring tool in an internal space, has an upper shielding body, a side periphery shielding body, and a lower shielding body, which form a magnetically shielded internal space of the magnetically shielded room. A pedestal has a higher rigidity than the lower shielding body, and is located on an under surface of the lower shielding body. First and second supporting members are located on and stand erect from the pedestal. The first and second supporting members penetrate the lower shielding body and extend into the internal space.

First claim

1 . A magnetically shielded room comprising:
an upper shielding body; a side periphery shielding body; a lower shielding body, wherein the upper shielding body, the side periphery shielding body, and the lower shielding body define a magnetically shielded internal space of the magnetically shielded room; a pedestal having a higher rigidity than the lower shielding body and located on an under surface of the lower shielding body; and a supporting member located on and standing erect from the pedestal, penetrating the lower shielding body, and extending into the internal space.

2 . The magnetically shielded room according to claim 1 , wherein
at least part of the supporting member contains a hollow part, the supporting member has an opening connected to the hollow part in an outer surface of the supporting member, and the magnetically shielded room further includes wirings extending in an upward direction or a downward direction through the supporting member.

3 . The magnetically shielded room according to claim 1 , further including a plurality of the supporting members located on and standing erect from the pedestal, wherein at least one of the supporting member is rod-like.

4 . The magnetically shielded room according to claim 1 , wherein the magnetically shielded room is movable.

5 . The magnetically shielded room according to claim 2 , further including a plurality of the supporting members located on and standing erect from the pedestal, wherein at least one of the supporting member is rod-like.
