The pin shaft portion 2 has a cylindrical shape, and its tip has a substantially truncated cone shape.

At the upper end of the intermediate portion 3, that is, at the portion connected to the pin shaft portion 2, a typical bolt head shape, that is, a flat hexagonal column portion is formed, and its peripheral surface serves as a tool such as a spanner. It forms an engaging portion 5 that engages. Here, the main axis of the hexagonal column is coaxial with the screw portion 4 and the like.

A flat hexagonal column portion is also formed at the lower end of the screw portion 4, and the peripheral surface thereof also forms the spanner engaging portion 6. The main axis of the hexagonal column is coaxial with the threaded portion 4, and the outer diameter of the hexagonal column is smaller than the inner diameter of the threaded groove of the threaded portion 4.

A nut portion 8 to be screwed with the screw portion 4 is formed on the rear side of the left corner of the front face of the bottom plate 7 of the vending machine housing. This has a through hole 30 formed in the bottom plate 7, a nut is applied from below the through hole, and is fixed to the bottom plate by welding or the like.

A case where the hinge pin 1 is attached to the bottom plate 7 will be described.

The screw portion 4 is passed through the through hole 30 and the nut portion 8
And the screw portion 4 are screwed together. In this case, a spanner is attached to the spanner engaging portion 5 in order to rotate the screw portion 4, and the entire hinge pin 1 is rotated by this spanner,
