[Problems to be solved by the invention]
However, recent vending machines tend to be of high storage type in which the product storage rack 59 is extended downward due to a demand for thinning. In this high storage type vending machine, the installation space for the heating device 51 is reduced by the extent that the product storage rack 59 extends downward, and therefore, the lower surface of the product storage rack 59 and the vending machine main body 58 are reduced. There may be a dimensional relationship in which the height (hereinafter, referred to as “width dimension”) H <b> 1 between the heating device 51 and the lower surface is lower than the height h of the heating device 51. In such a dimensional relationship, since the product storage rack 59 is in the way, the heating device 51 cannot be pulled out and the safety device 55 fixed to the heater box 52 from above cannot be accessed.
