When the main door 6 is further pressed, the state shown in FIG. 8 is reached and the state shown in FIG. 9 is reached, and the locking part 41 at the other end of the guide member 39 is locked by the guide member operating part 42. When the main door body 6 is further pressed in this locked state, the upper traveling body 17 provided at one end of the main traveling body 6 travels through the corner portion toward the storage rail portion 2 while one end of the main door body 6 is moved. The portion operates so as to protrude forward from the opening frame 16 (transition from the state of the broken line in FIG. 3 to the state of the dashed line). In this case, the main door body 6 is completely overlapped with the sub-door body 7, the lock by the lock member 36 is released, and the locking portion 14 is locked by the guide member operation portion 42. By pressing, the sub door body 7 jumps out forward while being overlapped and supported by the main door body 6. When the main door 6 is further pushed from the state of the dashed line in FIG. 3, the state becomes the state of the solid line in FIG. The state of this solid line indicates a state in which the upper traveling body 17 provided at one end of the main door body 6 has traveled to the distal end of the storage rail portion 2, and the state of the solid line is a state in which the opening 4 is fully opened. When the opening 4 is fully opened, the other upper traveling body 17 provided above the main door body 6 is located at the end of the opening frame rail portion 1, and the lower main traveling body 13 is located on the lower rail 12. Located at the end. Here, the lower main traveling body 1
3 does not protrude from the cutout portion 14. When the lower main traveling body 13 moves to the end of the lower rail 12 (that is, when the opening 4 is fully opened), the elastic locking member 85 is attached to the locked portion 13 a provided on the lower main traveling body 13. Elastically locks and temporarily locks the lower main traveling body 13. Therefore, the main door body 6 can be moved to the storage rail portion 2 to lock the state in which the opening 4 is fully opened, and the fully opened state can be maintained. By the way, in the full opening operation, a click feeling can be obtained when the elastic locking member 85 is elastically locked to the locked portion 13a, and the fully opened state can be confirmed by the click feeling.

On the other hand, to close the opening 4 from the fully opened state of the opening 4 shown by the solid line in FIG. 3, the main door body 6 is moved in the opposite direction from the state of the solid line in FIG. 13a is detached from the elastic locking member 85, and through the state shown by the dashed line in FIG.
The state shown by the broken line in FIG. In this case, since the locking portion 41 is locked to the guide member operating portion 42, when the main door body 6 moves, the sub-door body 7 also moves at the same time. In this manner, the sub-door 7 moves in a state overlapping with the main door 6, and the tapered portion 36a at the tip of the lock member 36 provided on the sub-door 7 hits the lower rail 12, and in this state, the sub-door 7 The main door body 6 is further moved in a state where
Is pressed in a state where the lock member 36 is in contact with the lower rail 12, the lock member 36 is lifted up, and the state shown in FIG. 8 is reached, the lock between the lock portion 14 and the guide member operation portion 42 is released, and the lock is released. The tip of the member 36 passes through the upper surface of the lower rail 12 and moves to a position where the lower end of the lock member 36 faces the lock receiver 43. In this state, the contact portion 35a provided at one end of the sub-door 7 hits the stopper 35. Therefore, when the main door 6 is further moved, the sub-door 7 does not move, and only the main door 6 moves. I do. In this case, during the closing operation, one upper traveling body 17 provided on the upper part of the main door body 6 and traveling on the storage rail section 2 is moved to the opening frame rail section 1.
Go to When the main door body 6 is moved, the state shown in FIG. 7 is changed to the state shown in FIG. 6, and the guide member operating section 42 is separated from the guide member 39 as shown in FIG. The lock is locked by being stuck in the lock receiver 43. Therefore, in this state, only the main door body 6 is moved and the other half of the opening 4 is opened and closed while the one half of the opening 4 is closed by the sub-door 7.
