The bolt 4 is screwed into a screw hole 22 formed in the convex portion 21a. At this time, the bolt 4 prevents the locking shaft 12 from falling off the receiving portion 21.
Therefore, in the state shown in FIG. 3, the cover 1 and the case 2 cannot be moved parallel to each other by the arms 11a and 11b on the cover 1 side, the locking shaft 12, and the receiving portion 21 and the bolt 4 on the case 2 side. An openable / closable hinge structure 3 is formed. Naturally, the hinge structure 3 can be opened and closed with the locking shaft 12 as an opening and closing shaft. The main part with the cover 1 opened is shown in FIG.

Next, from the state shown in FIG. 3 (a), as shown in FIG. 3 (b), when the cover 1 is closed and the two joining surfaces P1 and P2 are put together, a sealed box shape is obtained. The storage body 10 is formed.
Next, the bolts 5, 5, 5, 5 that are projected into the four through holes 52, 52, 52, 52 on the case 2 side are strongly attached to the screw holes 51, 51, 51, 51 on the cover 1 side. By screwing, as shown in FIG. 5, it is sealed so that wind and rain do not enter the inside.
Further, when locking, a lock (not shown) such as a padlock is locked through the through hole 53 on the cover 1 side and the through hole 54 on the case 2 side.

In this way, by closing and locking the cover 1 and the case 2, it is possible to prevent the internal devices from being stolen even when the storage body 10 is installed outdoors.
Even if all of the bolts 5, 5, 5, 5 are pulled out, the bolt 4 cannot be pulled out because the bolt 4 is covered with the base portion 13 of the arms 11 a, 11 b. Therefore, since the hinge structure 3 is maintained, the storage body 10 is prevented from being opened by the lock and the hinge mechanism 3.

In Embodiment 1 of the present invention, as shown in FIG. 3B, the receiving portion 21 opens in the direction from the center side of the case 2 toward the outside, and the bolt 4 is screwed to close the opening.
