As shown in FIG. 1, each of the guides 6 includes a guide portion 6a for guiding the end 4a of the shaft 4, and a groove 6b formed at a plurality of positions to lock the end 4b of the shaft 4. Each groove 6
When the end 4b of the shaft 4 is locked to the position b, the opening of the door 2 is gradually held corresponding to the locked position.

As shown in FIG. 2, the other leg 5b of the metal fitting 5 extends into the bottom wall 3, so that the upper surface thereof can at least face the guide 6a of the opening 6 and each groove 6b. Has become. That is, the upper surface of the leg 5b functions as a surface for receiving the tip of the end 4b of the shaft 4 inserted into the opening 6, and this surface itself is configured as a surface that may be damaged. The legs 5 a of the metal fitting 5 are directly fixed to the upper surface of the bottom wall 3 by joining means 7 such as screws or rivets. Therefore, the metal fitting 5 has a structure that does not substantially protrude above the bottom wall 3. In this embodiment, the metal fitting 5 is located on the upper surface of the bottom wall 3 only by the thickness of the leg 5 a. . That is, most of the metal fitting 5 is the bottom wall 3.
The structure is buried inside.

As shown in FIG. 1, components such as an electrical component box 8 and a drain plate (not shown) are arranged on the back side of the fitting 5 of the vending machine main body 1, for example.

In the door locking mechanism configured as described above, the end 4 b of the shaft 4 is connected to the guide 6 of the opening 6 of the metal fitting 5.

It is kept at that opening. At this time, the tip (lower end) of the end 4b of the shaft 4 is received by the lower leg 5b of the metal fitting 5, and comes into sliding contact with the upper surface. The end 4b of the shaft 4
Since the bottom wall 3 does not come into contact with the bottom wall 3, the bottom wall 3 is not damaged. Therefore, the leg 5b of the metal fitting 5 performs the same function as a conventional protection plate.

Since the metal fitting 5 does not substantially protrude from the upper surface side of the bottom wall 3, even when the electrical component box 8 or the drain plate disposed at the back thereof is pulled out, the parts are connected to the metal fitting 5. It is easily pulled out without interfering or getting caught on the metal fitting 5. Therefore, maintenance of these parts can be performed very easily.

As described above, the metal fitting 5 itself has both functions of locking the shaft end 4b and protecting the bottom wall 3 by receiving the tip of the shaft end 4b. The components can satisfy both functions of the conventional metal fittings and the protection plate. Therefore, the conventional two-part configuration can be made into a single part, the number of parts is reduced, and the assembling workability is improved and the cost is reduced.

Although the above embodiment has been described with respect to a vending machine, the present invention can be applied without limitation to the field as long as it has a similar door locking mechanism for a casing.
