On the other hand, on the floor side, a floor housing 97 that is the building housing 1 and a wall body 104 are provided, and the wall body 104 is erected from the upper surface of the floor housing 97. Further, an electromagnetic shielding material 96 made of an electromagnetic steel plate or the like and a floor finishing material 95 are laminated on the indoor side of the floor frame 97.

  And the upper part of the frame 2 is indirectly attached to the building frame 1 via the base suspension material 101 and the ceiling base 102 by fixing the upper holding frame member 20 to the lower surface of the ceiling base 102. It has been. The lower part of the frame body 2 is directly attached to the building frame 1 by fixing the lower holding frame member 20 to the upper end of the wall body 104.
