Description

  The present invention relates to a component mounting structure.

  For example, for components requiring relatively high mounting strength, such as a crescent for locking a shoji, the frame member is configured to have a cylindrical portion to which the component is mounted to improve rigidity and to have a cylindrical shape. A mounting structure in which a back plate is provided inside a portion (hereinafter, referred to as a cylindrical portion) is often used. That is, the component is attached to the frame member by screwing an attachment screw to the back plate via the component and the frame member. According to such a mounting structure, even if the frame material is formed of resin, the portion where the mounting screw is screwed is the back plate, and the back plate abuts against the frame material. Therefore, the mounting strength of the parts can be improved as compared with the mounting structure in which the mounting screws are screwed directly to the frame member (for example, see Patent Document 1).
