PROBLEM TO BE SOLVED: To reduce electromagnetic radiation from the door of an enclosure accommodating an electrical device by composing electromagnetic radiation shield by a conductive film being extended to the surface of a switching panel, elastically moving the film from its mounting position to a peripheral end, and mounting a magnetic means to the peripheral end of the film. SOLUTION: A box-type enclosure is provided with flanges 12 extended vertically to a side wall 10, which become a side pillar of the opening of a box. A lining 18 of a thin and flexible metal film is applied to the entire surface of the inner surface of a door 14 including a peripheral region 16. A channel 20 is extended along the peripheral region 16 and is in parallel with the end of a door 14. A magnet 22 is placed in the channel 20 with a margin, the flange 20 is made of such magnetic material as chrome steel, the magnet 22 attracts the flange 12 when the door 14 is closed, and a flexible metal strip 19 touches the flange 12. |
