A second locking portion may be provided.
FIG. 12 shows an example of a first locking portion that locks the sliding door member 111 in a state of being inserted into the hinged door member 112.
In the example of FIG. 12, a magnet M2 is provided at the door end of the sliding door member 111, and a magnetic body Mm is provided on the inner surface of the hinged door member 112 facing the magnet M2 to form a first locking portion. When the sliding door member 111 enters the hinged door member 112, the magnet M2 is attracted to the magnetic body Mm to lock the sliding door member 111 in the hinged door member 112.
Similarly, a second magnet is provided at the door end of the sliding door member 111, and a magnetic material is provided at the opening of the wall facing the magnet to lock the fully closed state in which the sliding door member protrudes from the hinged door member. The locking portion may be configured.
It should be noted that the first locking portion that locks the state in which one of the hinged door member and the sliding door member enters the other, and the fully closed state in which one of the hinged door member and the sliding door member protrudes from the other is locked. Any locking member capable of locking each material can be used as the second locking portion. For example, in a slide rail for slidably engaging a sliding door member 111 and a hinged door member 112, a first locking portion can be obtained by using a slide rail with a stopper that locks and holds the slide at a predetermined position. Alternatively, the second locking portion may be configured.

Further, the hinged door member and the sliding door member may be provided with different colors or patterns.
By making it possible to visually recognize that the hinged door member and the sliding door member are different members, it is easy for the operator (the person who opens and closes the opening / closing body) to recall the structure (opening / closing method) of the opening / closing body 11. can do.
