[Prior art and its problems]

 In this type of magnet catch, an attracting tool using magnets is built in between the substrate and the cover so as to be movable back and forth within a certain range, and the attracting end of the attracting tool projects from the opening of the front wall of the cover. The conventional magnet catch of this type is equipped with mounting plate parts that extend to both the left and right sides of the cover side, and the mounting plates provided on both mounting plate parts are connected to each other. It was configured to be attached to the furniture body using holes and wood screws.

In the conventional magnet catch as described above, when designing the appearance design of the magnet catch, it is an indispensable condition to provide mounting plate portions that project to the left and right sides, and it is possible to freely design the appearance design. Not only can it not be done, but since the mounting part is exposed when in use, there is a risk that it may spoil the aesthetics of furniture in use. Further, since the positioning part of the suction tool, the spring positioning part, etc. are integrally molded on the cover side where the mounting plate part is continuously provided, not only the design of the cover itself is restricted but also the cover is The cost was high, and it was difficult to construct a magnetic catch with a different design and color by replacing only the cover.
