2. Description of the Related Art There has been known a closet having a door attached thereto via a hinge or a hinge, such as a hanging closet used in a kitchen. Since the door of such a closet does not normally have a handle on the surface, the lower part of the door protruding below the main plate of the closet is touched to open the door. By the way, there are various inconveniences if the door opens when the door is closed and there is no intention to open it, when force is applied in the opening direction of the door. Occurs. For example, if the door of the cabinet closes unexpectedly during an earthquake, the contents may drop. Therefore, there is a need for a door opening / closing mechanism that is easily locked when the door is closed and is easily unlocked when the door is opened.

As a door opening / closing mechanism,
A door opening / closing mechanism as shown in FIGS. 30 and 31 has been known. Here, FIG. 30 is a perspective view of the door seen from the inside of the cabinet, and FIG. 31 is an explanatory view of the door opening / closing mechanism. This door opening / closing mechanism is composed of a door side mounting body 201 mounted on the back side of the door 2 and a main plate side mounting body 205 mounted on the lower surface of the main plate 5 of the cabinet.
