The lower transversely elastic airtight material 23 is formed of an elastic material into a long shape extending in the substantially horizontal direction, similar to the lower transversely elastic airtight material 13, and has a retractable mechanism on the lower end side of the second opening/closing body 20. (not shown), it protrudes and retracts from the lower end of the opening/closing body main body 21.
The lower transversely elastic airtight material 23 has both ends protruding laterally from the opening/closing body 21 while projecting downward from the opening/closing body 21 .

Therefore, when the first opening/closing body 10 and the second opening/closing body 20 are in the closed state, the door end side end of the lower transversely elastic air sealing material 23 is connected to the auxiliary air sealing material (not shown) on the lower end side of the vertical frame member 32. ). The lower lateral elastic airtight material 13 of the first opening/closing body 10 and the lower lateral elastic airtight material 23 of the second opening/closing body 20 have opposing ends in contact with each other.
