PROBLEM TO BE SOLVED: To provide a hinged door allowing the easy operation of a pivot hinge while preventing a hanging side airtight member from wearing early by turning of a door body in an out-of-plane direction.SOLUTION: A hanging vertical frame 1a of the door body 1 is constituted by mounting an attachment 20 detachably to a frame body 10, and the hanging side airtight member 5 is mounted to the attachment 20. The hanging side airtight member 5 is located inside in an in-plane direction from the turning center in the out-of-plane direction by the pivot hinge 3 of the door body 1, and when the door body 2 turns in the out-of-plane direction, the door body 2 does not contact the hanging side airtight member 5 to prevent the hanging side airtight member from wearing early. When the attachment 20 is removed, the hanging side end face of the door body 2 is exposed to the outside, and the pivot hinge 3 can be easily operated. |
