Claims

[Scope of utility model registration request]

A notch of the same shape is formed on the chassis to which the printed wiring board is attached, and on each rear edge of the casing body that houses this chassis, and on the inside rear of both sides of the lid body, which has a U-shaped cross section. In the mounting structure of a lid body in an electronic device housing in which a lid body is attached by engaging a protrusion and the lid body covers the housing body, the notch is formed into a circular hole and an opening is opened in the circular hole. The protrusion is formed with a groove having a width smaller than the diameter of the circular hole, and the width of the cross-sectional shape of the protrusion is formed to be slightly narrower than the diameter of the hole of the notch, and the thickness of the cross-section is set to be smaller than the diameter of the groove of the notch. The width of the lid is slightly thinner than the width of the lid, and the two protrusions are installed so that the width direction is not parallel to the top surface of the lid, and the lid is inserted into the notch formed in the housing body and chassis. When the lid is guided into engagement, the lid is spread out from the housing body, and the lid is engaged only along the width direction of the protrusion formed on the lid, so that the lid can be installed. Features a mounting structure for the lid in electronic device housings.
