Description

The present invention relates to a component mounting structure.

For example, for a part that requires relatively high mounting strength, such as a crescent that locks a shoji, the part where the part is attached to the frame material is made cylindrical to improve rigidity and is made cylindrical. A mounting structure in which a back plate is provided inside a portion (hereinafter referred to as a cylindrical portion) is often applied. That is, it is a structure in which the part is attached to the frame material by screwing the attachment screw into the back plate through the part and the frame material. According to such a mounting structure, even if the frame member is made of resin, the portion to which the mounting screw is screwed is the back plate, and the back plate is in surface contact with the frame member. Therefore, the mounting strength of the component can be improved as compared with the mounting structure in which the mounting screw is directly engaged with the frame member (see, for example, Patent Document 1).
