2. Description of the Related Art Conventionally, a plurality of doors are foldably disposed on an upper rail provided on a door frame via a suspension wheel, and on a lower rail provided on the door frame via a lower guide. There is a door (see FIGS. 4 to 6). At the ends of the upper and lower rails of the folding door, the end doors of the plurality of doors, which are arranged adjacent to the vertical frame of the door frame, are prevented from coming off the rails, and one end of the end doors is connected to the rails. A temporary fixing stopper for temporarily fixing detachably is fixed.

The temporary fixing stopper 9 is shown in FIG.
As shown in (A) and (B), a main body 91 having a circular bearing hole 911 for fitting a shaft provided in the end door and the temporary fixing stopper 9 are fixed to the rail. And a plate nut 922. The bearing hole 911 has an opening 912 that opens in the moving direction of the end door.

[0004] The temporary fixing stopper 9 is fixed to the ends of the upper rail and the lower rail attached to the upper frame and the lower frame of the door frame, respectively, and the shafts of the suspension wheel and the lower guide are inserted into bearing holes. By inserting, the folding door is temporarily fixed detachably. Therefore, normally, by temporarily fixing the end door, the folding door can be smoothly opened and closed.

On the other hand, by releasing the temporary fixing of the end door, the end door itself can be moved toward the other end, and the end of the opening of the door frame can be widely opened (FIG. 5).
reference). Thus, for example, when the folding door is used as a door of a storage or the like, there is an advantage that loading and unloading of luggage at the end of the storage, and putting in and out of a drawer of a chest can be easily performed.

[0006]

However, the temporary fixing stopper 9 has the following problems. That is, as shown in FIG. 16, when the door frame 7 is distorted, the pair of temporary fixing stoppers fixed to the ends of the upper and lower rails are arranged at positions shifted from the vertical line. The bearing hole 911 of the temporary fixing stopper 9 has a circular shape having a diameter substantially equal to the diameter of the cylindrical shaft portion.

Therefore, when the door frame 7 is distorted as described above, when the end door 21 is temporarily fixed to the temporary fixing stopper 9, the end door 21 becomes oblique, and the end door 21 becomes oblique. A gap 8 is formed between the upper frame 71 and the lower frame 72 of the door frame 7 at the upper end and the lower end of the door frame 7. As a result, the appearance is deteriorated, and excessive force is applied to the suspension wheel and the lower guide, which may cause a failure.

The present invention has been made in view of such a conventional problem, and even when the door frame is distorted, the door can be temporarily fixed horizontally at the ends of the upper and lower rails. It is an object to provide a folding door having a fixing stopper.
