The main door body 30 and the central airtight member 133 are installed in close contact with each other. Further, as shown in FIGS. 7 and 8, in the state in which the main door body 30 is translated by a predetermined distance D in a state in which it cannot rotate, as described above, the elastic member 170 of the connecting portion 140 The third side piece 131c of the summing part main body 131 and the first groove side piece of the groove part 134 are obtained by fixing the position of the indoor side summing part 130 with respect to the frame 10 by the fixing part 132 while allowing deformation. The distance between each of 134a and the main door body 30 is the interval length L2 (that is, the main door body 30 is connected to the summing unit main body 131 more than the state before the main door body 30 is translated. The main door body 30 and the central airtight member 133 are in close contact with each other while maintaining the distance L2 regardless of the relative movement of the child door body 80. Before translating By the parent door body 30 is a central air-tight material 133 is disposed in a position deformed by being pressed than state. Even if the position of the child door body main body 80 is moved relative to the frame body 10 by moving the child door body body 80 relative to each other in the non-rotatable state due to such an installation position, the indoor side calling with respect to the frame body 10 is performed. The position of the mating portion 130 can be maintained at a position where it can be in close contact with the main door body 30. Further, when the main door body 30 is translated in a state where the main door body 30 is translated, the central airtight member 133 is pressed and deformed by the main door body 30 with respect to the position of the indoor side summing unit 130 with respect to the frame body 10.
