In this configuration, if it is possible to secure even a surface on which a flat hinge can be attached, for example, a folding door can be easily configured by using a door body used for a sliding door, but in a deployed state, adjacent to each other. The end faces of the adjacent sides of the two door bodies that are in the state are exposed to the front side in the folded state, and in this folded state, a gap is likely to occur between the adjacent sides of the two door bodies, and the unfolded state is developed. There is a problem that a fingertip may be pinched between the end surfaces of the adjacent sides of the two door bodies during the operation of switching to the state.

  As a folding door that can solve the above problems, a vertical belt-shaped intermediate member is interposed between two door bodies, and both sides of the intermediate member and the two door bodies rotate vertically. A configuration of a folding door that is rotatably connected around an axis is considered. When this configuration is adopted, a spur gear is fixed to each of the two door main bodies so as to be concentric with the two vertical rotation shafts arranged in parallel so that the two door main bodies open and close symmetrically. Interlocking interlocking structure is used at the same time, but the problem is that the general door body used for sliding doors cannot be diverted as it is, and the adjacent sides of each of the two door bodies are special. It is necessary to prepare a dedicated door body with a structure, and a significant increase in cost is inevitable.

  An object of the present invention is to provide a folding door that can solve the conventional problems as described above, and its means is shown with reference numerals of embodiments to be described later. A folding door formed by connecting door bodies 1A and 1B so as to be foldable with each other, and includes two hinge members 26a and 26b, a cover member 29 between the door bodies 1A and 1B, and a pair of end members 31a and 31b.
