Description of the invention (I) [Technical field to which the invention belongs] For example, locks such as drawers, bookshelves, sliding doors, and roll-up doors of cabinets are provided on the sliding side of the furniture. The cabinet of the representative example will be described. If the locking operation is performed with the drawer pulled out, and the drawer is closed without paying attention, the top plate or side plate on the body side will be damaged, or the latch plate, front panel, etc. will be deformed. . The present invention relates to a false lock prevention device for furniture which can prevent the aforementioned problems. [Prior Art] For sliding-type drawers or furniture with locks on the door side, a false lock prevention device for furniture has been previously proposed (refer to Japanese Patent Laid-Open Publication No. 7-26543). When the drawer or door is opened, The guide spring is used to make the malfunction guide (for restricting the advancement and retreat of the latch for the lock) protruding. When the drawer or the door is closed, the malfunction guide is pressed by the fixed part such as the front part of the side plate of the body to resist the malfunction. The elasticity of the guide guide spring makes it no longer protrude, thereby lifting the restriction on the advancement and retreat of the latch for the lock head. However, in the aforementioned prior art, although a false lock prevention device is installed on the furniture, the lock pin for the special shape is inserted into the reinforcing plate in front of the side plate by the operation of the key. However, the lock is locked by the latch pin. The distance between the part and the part that is actuated by operating the lock is very long, so the reliability of its action is poor. As a result, when the drawer is closed, the main body side of the furniture is often damaged or deformed, and there are still problems. The present invention has been made in view of this problem, and an object thereof is to provide a false lock prevention device. In order to restrict the advancement and retreat of the mortise lock plate, a convex button portion is provided on the locking plate through a spring so that the convex button portion is opposed to the locking plate.
