To simplify a chute structure for introducing a commodity to be ejected from a commodity housing rack to the commodity ejection port of a heat insulating door by suppressing the height directional clearance of the commodity housing rack and the chute to the absolute minimum to maintain space efficiency in a high status by using unadjusted type mechanical characteristics.

An unadjusted type commodity ejection unit B equipped with a lower stopper and an upper stopper for receiving various types of commodity 5 whose diameters are different is installed at the lower part of each commodity housing rack C. A chute 17 is configured for receiving the commodity 5 to be ejected from the commodity ejection unit B, and for ejecting and guiding the commodity 5 toward a commodity ejection port 7 of a heat insulating door 8, wherein a second chute section 17B positioned just under a second commodity housing rack group of the adjacent column of a first chute section 17A positioned just under a first commodity housing rack group of columns corresponding to forward and backward directions at the commodity ejection port 7 is configured in a horizontal inclined attitude so that the commodity 5 to be ejected from the second commodity housing rack group can be laterally conveyed to the first chute section 17A.
