た。In the case of the drawing structure illustrated in FIG. 6, the weight can be reduced because the strength can be ensured even with a thin sheet metal, but the cost is increased because a molding die is required. On the other hand, in the bending structure illustrated in FIG. 7, it is difficult to reduce the weight because the strength cannot be secured unless the sheet metal is thick. However, the cost is reduced because a molding die is not required.
Thus, both the drawing structure and the bending structure have advantages and disadvantages.

制される。Means for Solving the Problems and Effects of the Invention A housing according to the first aspect of the present invention for solving the above-mentioned problem is manufactured by bending a single sheet metal to form a bottom or ceiling. A side plate disposed along the outer periphery of the flat plate portion, a projection is continuously provided on some of the side plates, and the protrusion is provided with an engagement hole or the protrusion provided in the flat plate portion. Since the side plate having the protrusion is engaged with the engagement hole provided in the side plate adjacent to the side plate having the protrusion, the deformation of the side plate having the protrusion is restricted by the engagement between the protrusion and the flat plate or the adjacent side plate. Is done.

Thereby, a thin sheet metal can be used, and the weight can be reduced. In addition, bending is low-cost as described above. Therefore,
A low-cost and lightweight sheet metal housing can be provided.

側板の一方に突起部を連設し、他方には係合穴を設けて
おき、突起部を係合穴に係合させればよい。In the case where a single sheet metal is bent to form a housing, for example, a structure in which a flat plate portion is rectangular and side plates are bent at four sides of the rectangular shape may be considered. In this case, a protrusion may be provided on one of the adjacent side plates, and an engagement hole may be provided on the other, and the protrusion may be engaged with the engagement hole.

In order to connect the first side plate and the flat plate portion, the fold between the second side plate and the first side plate is firstly folded, and then the first side plate and the flat plate portion are engaged. Fold the crease of the mountain. Since the projection can be engaged with the engagement hole during the latter mountain folding, the processing procedure is not complicated.

る。Further, in the case according to the first or second aspect, it is preferable that the protrusion is elastically deformed when inserted into the engagement hole, and is elastically restored when the engagement is completed to maintain the engagement. Since the projections are made of sheet metal (the entire housing), it is easy to elastically deform the projections. In order to maintain the engagement, for example, as in claim 3, in the casing according to claim 1 or 2, the protrusion has a fold (for example, a valley) on the side where the engagement is released as a resistance. Is preferably provided. Further, such a front end side of the fold is more advantageous because it also functions as a guide surface when inserting the projection into the engagement hole.

る。After the state shown in FIG. 4, the fold 13a between the ceiling 10 and the side plate 13 is mountain-folded to about 90 degrees. When the fold 13a is folded in a mountain, each projection 11 approaches the corresponding engagement hole 12, and first the guide surface 11d enters the engagement hole 12. When the bending of the fold 13a progresses,
Since the guide surface 11d contacts the edge 12a of the engagement hole 12,
As a result, the guide surface 11d and the engagement surface 11e are elastically deformed to the side indicated by the arrow A in FIG. Then, when the fold 11c passes through the edge 12a of the engagement hole 12, the guide surface 11d and the engagement surface 11e elastically return to the side indicated by the arrow B in FIG. 3, and the edge 12a of the engagement hole 12 becomes the fold 11b. (The state shown in FIG. 3). As a result, the edge 12a of the engagement hole 12 is sandwiched between the engagement surface 11e and the laminated surface 11f, and the engagement surface 11e (the portion along the fold line 11b) is locked to the edge 12a of the engagement hole 12. . Further, the laminated surface 11f is in close contact with the inner surface of the ceiling 10.

Presses itself against the edge 12a of the engagement hole 12 by its elastic force. Therefore, the engagement surface 11e and the edge 12a of the engagement hole 12 are in strong contact, and the engagement between the engagement surface 11e and the engagement hole 12 is not loosened or rattled.

トであるから、筐体２０のコストも低減できる。As described above, the side plate 13 is connected to the ceiling 10 at the fold 13a, and the side plate 1 connected to the side plate 13 is provided.
4 and 15 are connected to the ceiling 10 by the engagement between the projections 11 and the engagement holes 12, respectively, so that the side plates 13, 14, 15
The resistance to the deformation by the external force, that is, the strength, is extremely improved. Thereby, a thin sheet metal can be used, and the weight of the housing 20 can be reduced. Further, since the bending process is low cost, the cost of the housing 20 can be reduced.

Is engaged with the engagement hole 12, so that the processing procedure is not complicated. In particular, since the guide surface 11d is provided on the tip side of the protrusion 11, the protrusion 11 can be smoothly and reliably inserted into the engagement hole 12. Moreover, even after the engagement, the elastic deformation of the protrusion 11 (the engagement surface 11e) remains, and loosening and release of the engagement are reliably prevented, so that the strength of the housing 20 does not decrease.
