发明名称 ELECTROMAGNETIC SHIELDING SHUTTER
摘要 PROBLEM TO BE SOLVED: To provide an electromagnetic shielding shutter which has so good electromagnetic shielding performance that it can be set at an opening of an electromagnetically shielded space. SOLUTION: A shutter curtain 3 is constructed by connecting a plurality of metallic slats 4 together in a manner vertically overlapping each other, and a base board 5 on an under bed of the shutter curtain has an electrically conductive braided wire 6 arranged thereon. The shutter has a pressing devices 8 including a plurality of pressing portions 8a which are arranged at desirable intervals in a longitudinal direction of a guide rail 1 and protrude toward the interior of a groove of the guide rail. When the opening is fully closed, right and left edges of the shutter curtain are pressed toward inner walls of the guide rail by the pressing device 8, and therefore the shutter curtain is connected to a shielding layer of a building, whereby the braided wire 6 is connected to the shielding layer of the building via a backing plate 9 arranged on a floor surface.
