摘要： PROBLEM TO BE SOLVED: To realize favorable electromagnetic shielding performance without forming a difference in level at an entrance. SOLUTION: A device is provided with a slide rod 31 to be mounted on a door main body 20, an interlock mechanism 40 to be connected to the slide rod 31, and a closing member 51 provided with shield packings 52, 52 to be assembled into the door main body 20 to freely elevate. The interlock mechanism 40 lowers the closing member 51 by move of the slide rod 31 in the thickness direction of the door main body 20 when the door main body 20 is pressed to a door frame, and the closing member 51 closes a gap between a lower end of the door main body 20 and the door frame to shield.

摘要： PURPOSE: To improve airtightness and watertightness, and realize excellent electromagnetic wave shielding performance without requiring an opening-closing space by driving a sliding door in a closing position to the door frame side by pressing mechanisms, and bringing them into close contact with each other. CONSTITUTION: An electromagnetic shielding sliding door 20 to open and close the front of a door frame 10 through suspending door wheels 22, is arranged in front of the door frame 10 where shielding packing 16 and 16 is added to the front. This sliding door 20 is movably suspended in the longitudinal direction through slidingly movable bearings 23 and 23 interposed between it and the suspending door wheels 22. In a lower frame material 11 of the door frame 10, the whole is embedded in a floor surface. A guide roller to engage with a guide member under the sliding door 20 is arranged on the door frame 10, and a longitudinal movement of the sliding door 20 in a closing position is allowed by the guide member and the guide roller. The sliding door 20 in a closing position is driven to the door frame 10 side by pressing mechanisms housed in left and right vertical frames 33 and 33, and is pressed against and brought into close contact with the front of the door frame 10.
