Improvement can be realized.
In addition, since the assembly is performed by inserting the claw piece 10 into the slit 11, positioning work such as matching the bolt holes is not necessary. Therefore, it is possible to realize an improvement in work efficiency associated with further ease of assembly work.

Moreover, according to the said storage box 1, since each slit 11 is formed so that it may become a dimension substantially the same as the width | variety and thickness of the nail | claw piece 10, the play of the nail | claw piece 10 in the insertion state is minimized. Can be prevented, and rattling can be eliminated.
Furthermore, since both plate members are fixed using the reinforcing metal fittings 20 after the plate members are connected to each other, the rigidity of the storage box 1 in the assembled state can be increased, and each plate member is formed thinly. In addition, since the rigidity can be maintained, it is possible to expect effects such as improvement in workability and cost reduction during transportation / storage work accompanying the thinning of each plate member.

Further, the projections 15, 15... Are provided on each plate member side, and the round holes 22, 22... Are provided in the reinforcing bracket 20, and the projections 15 are fitted into the respective round holes 22. Therefore, the bolt hole 23 and the bolt insertion hole 16 are automatically positioned by the fitting, the fixing work of the reinforcing bracket 20 is facilitated, and the efficiency of the assembly work can be improved. Although only two places are bolted, a sufficient reinforcing effect can be expected. Further, since the reinforcing metal fitting 20 is attached to the inner surface of the flange portion F formed on the periphery of the front opening, it does not interfere with the installation work of the electric device in the storage box 1.
In addition, the top plate 3, the side plates 4, 4, the bottom plate 5, and the back plate 6 are formed into a box-like body having bent portions R obtained by bending each of the peripheral portions of the metal plate-like members for reinforcement. Since it is formed, it is possible to improve the rigidity of the storage box 1 in one layer and to reduce the thickness of each plate member accompanying the improvement in rigidity.

  In addition, the structure which concerns on the storage box of this invention is not limited to the aspect as described in the said embodiment at all, The shape of each board member, the number of a slit or a nail | claw piece, an installation position, the shape of a bending part, etc. The structure which concerns on can be suitably changed as needed in the range which does not deviate from the meaning of this invention.

  For example, it is possible to appropriately change whether each plate member is provided with a slit or a claw piece (for example, unlike the above embodiment, there is no problem if a claw piece is provided on the bottom plate and a slit is provided on the side plate). It is also possible to provide both a claw piece and a slit (for example, a claw piece is provided at the front portion of the bent portion of the lower edge of the side plate, and a slit is provided at the rear portion).

Moreover, there is no problem even if the reinforcing metal fitting is attached to the inner surface of the bent portion on the back plate side.
Furthermore, in the said embodiment, although plate members are assembled | attached by a slit and a nail | claw piece, sealing members, such as a double-sided tape, are stuck on a bending part etc., for example, and plate members are connected by this seal member ( Or a seal member may be used in addition to the slit and the claw piece.

Furthermore, the shape of the panel mounting member can be changed as appropriate, and the left and right panel mounting members described in the above embodiments may be integrally formed as one panel mounting member, or at the four corners of the back plate. A configuration may be employed in which independent panel mounting members are provided (for example, panel mounting members such as those obtained by further dividing the panel mounting member described in the embodiment in the vertical direction are provided at the four corners of the back plate). In addition, the panel mounting member and / or the back plate may be provided with a locking portion or the like that can lock the panel mounting member in the mounted state on the back plate. You may open the hole for inserting.
In addition, for example, when the reinforcing member has a sufficient thickness, the fitting portion may be a fitting recess (bottomed hole) instead of a round hole. In addition, it is possible to provide a highly versatile reinforcing member by providing more fitting portions on the reinforcing member and selecting a fitting portion to be used depending on the size or shape of the storage box.
