SHIELDING DOOR

摘要

PROBLEM TO BE SOLVED: To provide a high shielding effect by preventing wear of a shield member disposed on a door. SOLUTION: The shielding door has support 30 and a door part 50 supported against the support 30. The support 30 is movable between an open position where it opens an opening and a closed position near the opening. The door part 50 is provided with the shield member located in a position where it makes contact with the wall surface of a side where a door frame is not provided, the door part 50 being movable relative to the support 30 between a non-contact position where a predetermined gap is formed between the shield member and the wall surface of the side where the door frame is not provided and a contact position where the shield member makes contact with the wall surface of the side where the door frame is not provided. When the support 30 is in the closed position and the door part 50 in the contact position, the opening 70 is shielded by the door part 50.
