As shown in FIG. 7, the mounting member P is applied to the upper surface E of the storage main body C and the upper surface F of the door D, and is also applied to the lower surface G of the storage main body C and the lower surface H of the door D. Guess
Bolts A are inserted into the insertion holes of the housing main body C, and bolts B are inserted into the insertion holes of the door D, respectively, so as to protrude to the inside of the housing main body C and the door D, and nuts L are inserted into the protruding portions of the bolts A and B. The hinge stay for the storage is fixed to the storage main body C and the door D by screwing or inserting the stopper pin M. FIG.
O is packing on the main body side, and Q is packing on the door side.
These packings O and Q are for making the housing main body C and the door D adhere to each other, and are made of resin or rubber.

[0004]

The conventional hinge stay for a storage has the following problems. (1) Bolts are press-fitted into the mounting member P, but if a strong external force is applied to the bolts or pins, they may rotate or come off. (2) Since the storage body C and the door D are lowered by their own weights, a gap is easily formed between the upper surfaces E and F and the storage hinge stay above. If there is a gap, insert a steel cutter, iron scissors, iron saw or the like into the gap, cut the shaft J of the main body bolt A or the door bolt B, and store the main body C of the storage.
The door D can be removed from the storage box, and goods and money stored in the storage main body C can be robbed. When a gap is formed above the storage main body C and the door D as described above, a bar-like material is provided between the bottom surfaces G and H of the storage main body C and the door D and the lower storage hinge hinge stay. Pry the jig and put the storage body C
And the door D is pushed up, and the gap I can be made in the lower part. When the gap I is formed, an iron cutter, iron scissors, an iron saw, and the like are inserted from the gap I to cut the shaft portion J of the main body bolt A or the door bolt B, and remove the door D from the storage main body C, Items and money stored in the storage main body C can also be robbed. In recent years, this type of theft has increased. (3) Conventionally, bolts A and B are used to prevent theft.
After that, the shaft portions J are subjected to induction hardening to harden the shaft portions J so that the shaft portions J are not cut by an iron cutter or an iron saw. In this case, a portion cut with an iron cutter, iron scissors, an iron saw, etc., that is,
It is desirable to perform induction hardening up to the root of the shaft portion J. However, when doing so, the projection for spot welding protruding inside the head K of the bolts A and B hardens, and the projection is hard to be welded to the mounting member P. Therefore, the bolts A and B spot-welded to the mounting member P are easily separated from the mounting member P, and a gap is easily formed between the storage main body C and the door D and the storage hinge hinge stay. In order to solve this problem, when induction hardening is performed so that the spot welding protrusion does not harden, the high frequency hardening is not performed up to the neck of the shaft portion J. , Iron saws and the like. (4) When bolts A and B are welded to mounting member P by ordinary welding instead of spot welding, high-frequency quenching can be performed up to the neck of shaft portion J. There are no difficulties, but the heat of the welding oxidizes and destroys the internal structure of the material, which contributes to its weakness to impact. Further, there is a problem that the welded portion is easily peeled off due to vibration or the like.
