なる。 A radio-shielded room inevitably has a storage entrance. This storage door is provided in the storage door panel, and usually has a swinging door attached to it. When performing work such as electrical discharge machining in a radio-shielded room, if radio waves leak outside from between the door and the door, it will cause radio interference to TVs and other devices. By the way, the storage entrance panel and the door are generally equipped with metal plates, and in order to eliminate the above-mentioned radio interference in such cases, when the door is closed, the metal plate of the storage entrance panel and the metal plate of the door should be separated. It is already known that the connection can be made electrically. Conventionally, therefore, a metal door support member that is electrically connected to the metal plate of the storage door panel is attached to the periphery of the storage door of the storage door panel, and a current-carrying plate is attached to the surface of the door support member that faces the storage door. , a thin electrically conductive claw made of beryllium copper was attached to the periphery of the door, protruding from the door and electrically connected to the metal plate of the door. Also, when the door was closed, the claw came into contact with the electrically conductive plate. However,
Due to long-term use, the tabs may become deformed or broken, causing poor contact at that point and causing radio waves to leak. Moreover, if the nails become deformed or broken, they must be replaced.
I have a grievance that the work will be troublesome. In addition, the claws are visible when the door is opened, making the door unsightly.
