When removing the elastic piece 5, the amount of elastic deformation of the elastic piece 5 is large, and in order to secure this, the space between the side end 2b of the cover 2 and the guard piece 4 must be formed sufficiently large. There is a problem that a space for disposing the substrate 8 becomes narrow.

った。In addition, forming the elastic piece portion 5 having a large deformation amount on the cover 2 requires increasing the thickness of the cover 2 itself as well as the elastic piece portion, thereby increasing the strength.
Bezel amount B is the thickness of the casing 1 of the opening edge 1a to the upper surface of the cover 2 no longer, dust is easily deposited on this portion.
Therefore, for example, during work in a clean room, the accumulated dust scatters and adheres to the product, which has a serious adverse effect. In addition, the elastic piece portion 5 needs a large amount of deformation, so that the length of the elastic piece portion 5 becomes long, and the amount of insertion into the case is large. This poses a problem that the mounting of the wiring board provided inside the case is limited.

と取り外しが完了する。On the other hand, when removing the cover 21, the pressing projection 14 of the elastic piece 12 is pressed toward the inside of the case 11. Then, the elastic piece portion 12 is elastically deformed in the pressing direction, so that the engagement between the outwardly engaging portion 13 and the inwardly engaged portion 24 is released. When the cover 21 is separated from this state, the removal is completed. .

The engagement between the engagement portions 13 and 24 can be released only by slightly deforming. As described above, since the amount of deformation of the elastic piece 12 can be reduced, the space between the side end 21b of the cover 21 and the guard piece 23 can be narrowed. A large space between the portion 23, that is, a space for disposing the substrate 26 can be ensured.

う効果がある。As described above, according to the present invention, the elastic piece is formed integrally with the case, and the case-side engaging portion is formed on the elastic piece on the opening end side of the case rather than the pressing projection. Therefore, the engagement of the case-side engaging portion can be released by slightly deforming the elastic piece portion. Accordingly, since it reduces the amount of deformation of the elastic piece portion, cable
Space for the substrate disposed within the scan Ru can be widely ensured. Also, the elastic piece was formed integrally with the case .
In, it does not require a rigidity to the cover itself. For this reason, the hippopotamus
It is possible to reduce the thickness of the over, bezel amount B shown in FIG. 2 'is made thinner than the conventional bezel amount B shown in FIG. 4, it is also reduced deposition of dust. As a result, when working in a clean room, there is an effect that it is possible to reduce adverse effects due to scattering of dust. Moreover, since the elastic piece is provided in the case, the amount of insertion of the cover into the case can be reduced, and there is an effect that there is no inconvenience of restricting the assembly of the wiring board provided inside the case.
