By the way, since the heat insulating wall is fixed to the vending machine main body integrally, and the notch formed in the heat insulating wall does not move, the heat insulating wall is not moved. There is no problem in inserting and crossing the harness.

However, in recent years, in order to be able to easily change the storage ratio between cold products and hot products, the heat insulating wall is formed of a heat insulating partition plate which can slide back and forth, and the heat insulating partition plate is formed of each column. A vending machine has been proposed in which a storage ratio is changed by being inserted into and removed from a support rail between the vending machines.

According to this vending machine, each time the heat insulating partition plate is inserted or removed, the heat insulating partition plate moves back and forth through the support rail. For this reason, even if a notch for crossing the harness is provided in the heat insulating partition plate, a harness that refuses to break can not be wired in this notch.

[0008] In view of the above-mentioned conventional problems, an object of the present invention is to provide:
It is an object of the present invention to provide a vending machine which does not break the electric wiring even when inserting and removing the heat insulating partition plate.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention has a plurality of product storage columns arranged in a product storage with a gap therebetween, and a thermally insulating insulation which can be inserted into and removed from the gap through a support rail. In a vending machine in which a partition plate is inserted and a plurality of rooms of different temperature zones are formed in a product storage, a harness for electric wiring is traversed through a support rail, and at least an upper peripheral side surface of a crossing portion of the harness. Is covered with a harness protection member.

According to the present invention, since the harness is passed through the support rail fixed to the product storage, the harness is fixed by the support rail.
Since the upper peripheral side surface of the harness is covered with the harness protection member, even when the heat insulating partition plate moves on the support rail, the heat insulating partition plate does not contact the harness, and the electric wiring does not break.
