It may consist of a hinged door and a small door that is normally not open to lock the hinged door and only narrows the doorway. The door, which is composed of one hinged door and a small door, forms a relatively narrow doorway by opening only the hinged door during normal times when people enter and leave, and also carries in and out relatively large luggage. In some cases, a wide doorway can be formed by opening both a hinged door and a small door, and it is widely used as a doorway and a doorway of a room where luggage is frequently taken in and out.

Conventionally, in order to construct a door composed of a hinged door and a small door as shown in FIGS. 5 and 6, for example, the hinged door 1 is one of the vertical frames 5a of the frame body 5 forming the opening of the building. A small door provided with a hinge 9 at one end face thereof via a hinge 9 and provided with a French dropout in the vicinity of the side end face on the side of the hinged door 1 so that a locking rod can project outward from the upper end face and / or the lower end face. 2 is attached to the other vertical frame 5a of the frame body 5 at its one end face 2a via a hinge 9, and the French dropping locking rod is projected from the end face of the small door 2 to make the upper frame of the frame body 5 5b and / or the recesses formed in the lower frame or floor 5c were inserted and locked. However, in the work of attaching the small door 2 to such a door, the small door 2 must be attached to the vertical frame 5a of the frame body 5 through the hinge 9, so that the small door 2 can be hung or cut at the site. Since the number 9 has to be screwed, there is a drawback that it takes time and labor.

Further, when loading or unloading a relatively large load, that is, a load wider than the opening formed by opening only the hinged door 1, a small opening 2 should be opened together with the hinged door 1 to form a wide opening. However, if the small door 2 cannot be rotated 180 °, the space near the hinge 9 side end of the small door 2 is the space of the opening formed by the frame 5 as shown in FIG. There is a drawback in that the opening formed by opening the hinged door 1 and the small door 2 becomes considerably narrower than the opening formed by the frame body 5 because of the protruding state. Further, between the small door 2 and the vertical frame 5a of the frame body 5, a hinge 9 appears on at least one side, so that the small door 2
However, there was a drawback that the design of the car would be impaired.
