By inserting the screw 13b into the door and removing the screw 13b by screwing it off, the bracket 13 together with the guide roller 14 becomes free from the door end side door body 9, whereby the folding door 5 becomes the door end side and the door end side door body 9 , 7 is a single plate (flat plate), and the pivot hinge 6 can be used as an axis for emergency opening operation to the outside of the room.

Further, in the present embodiment, the folding door 5 is urgently opened by removing the support shaft 14a from the bracket 13 in addition to the case where the bracket 13 is removed from the door end side door body 9 when the abnormal state occurs. It is considered so that it can be done.
That is, when the abnormal state occurs, a tool (not shown) such as a spanner is inserted from the gap X between the guide rail 12 and the door end side door body 9 and the tool is locked to the locking portion. By turning the support shaft 14a and pulling out the support shaft 14a from the bracket 13, the guide roller 14 becomes free from the door end side door body 9, and even in this way, the folding door 5 can be moved to the door end side and the door end side. With the doors 9 and 7 on the door tail side forming a single plate (flat plate), the pivot hinge 6 can be used as the axis for emergency opening operation to the outside of the room. When the support shaft 14a is pulled out from the bracket 13 in this way, the guide roller 14 moves upward, but the range of the storage space Y provided between the guide roller 14 and the upper piece portion 12d in the guide rail 12. The guide roller 14 is set to move upward inside, so that the guide roller 14 is not hindered from being pulled out. When the guide roller 14 is removed together with the bracket 13, the guide roller 14 may enter the storage space Y when the bracket 13 is lifted, which may hinder the lifting operation. There is no such thing.

In the present embodiment configured as described above, the folding door 5 opens and closes the doorway E by operating in a state where the door bodies 7 and 9 on the door tail side and the door tip side are folded indoors. However, when an abnormal situation occurs in the room where the user collapses and the folding door 5 cannot be opened or closed, and there is a tool G such as a screwdriver, the tool G is used on the ceiling surface H. By inserting the guide roller 14 into the insertion hole 12k formed in the guide rail 12 from the space S between the guide rail 12 and the guide rail 12 and removing the screw 13b, the guide roller 14 is separated from the door end side door body 9 together with the bracket 13. Then, it becomes free from the door end side door body 9. As a result, the regulation of the door end side door body 9 by the guide roller 14 is released, and the restraint (restraint) of the movement in the front-rear direction from the guide rail 12 is removed. As a result, the folding door 5 is the door tail. It is possible to open the doors 7 and 9 on the side and the door end to the outside of the room in a single piece, and to quickly perform rescue work such as removing the fallen user from the toilet booth 1.
