Japanese Unexamined Patent Application Publication No. 2003-367 Japanese Patent No. 3090408

In the case of such a conventionally known slide hinge, when the door body to which the connecting housing is attached is made of a solid wooden material, the mounting screws can be tightened and the door body can be easily removed from the connecting housing. However, in recent years, many of the door bodies use a board with a honeycomb structure made of corrugated cardboard as a core material that does not allow mounting screws to work very well, and a thin decorative board such as plywood is attached to both sides of the board. It is ready to be used.

In such a case, even if an attempt is made to fix the connecting housing of the slide hinge attached to the door body side with mounting screws, since the core material is the honeycomb structure board made of corrugated cardboard, which is not very screwable, the connection is difficult. There is a problem that the housing for connection cannot be firmly fixed to the door, or the housing for connection falls off from the door during use after being fixed.

Therefore, Kato Electric Co., Ltd., an affiliated company of the applicant of the present application, has developed a connecting housing even if it is a door body using a board with a honeycomb structure made of corrugated cardboard or a cabinet body that does not screw the core material. We have proposed an inexpensive slide hinge that can be easily attached and is designed so that there is no fear of falling off after attachment (Japanese Patent Application Laid-Open No. 2014-88755). The slide hinge according to the prior application has an excellent structure in which the connection housing of the slide hinge can be attached to the board of the honeycomb structure with one touch without using mounting screws or the like. If the means is made of synthetic resin, the strength remains unreliable. Therefore, it is necessary to use an expensive resin material or use a thick housing, resulting in an expensive product. There has been a demand for countermeasures against the fact that the housing for connection becomes large only at the portion where the thickness is increased.
