PROBLEM TO BE SOLVED: To provide a door which can improve air tightness.SOLUTION: A door 1 comprises a master door body 20 and a slave door body 70. In the door 1, the master door body 20 comprises a master door body main body 30, and the slave door body 70 comprises a slave door body main body 80, an indoor-side alignment part 130 which covers a clearance between the master door body main body 30 and the slave door body main body 80 in an opening-part full-closed state, and a connection part 140 which connects the indoor-side alignment part 130 to the slave door body main body 80. The connection part 140 connects the indoor-side alignment part 130 to the slave body main body 80 so that the slave door body main body 80 becomes turnable together with the indoor-side alignment part 130 in a turnable state, and in a non-turnable state, maintains a position of the indoor-side alignment part 130 with respect to a frame body in a position where the indoor-side alignment part 130 can come into tight contact with the master body main body 30 even if a position of the slave door body main body 80 with respect to the frame body is moved by making the slave door body main body 80 relatively movable to the indoor-side alignment part 130.SELECTED DRAWING: Figure 2 |
