PROBLEM TO BE SOLVED: To make a sealed structure of partition plates and an interior door maintain air tight for a long period, when a commodity housing chamber as a heat-insulating chamber of a vending machine is partitioned into a plurality of small chambers arranged from side to side by the heat-insulating partition plates. SOLUTION: The interior door 3 is provided with a protruded member A13 which has a protruded shape and extends from the bottom to the top so that the member hermetically abuts with a packing 12 fastened to the partition plates 5, so that adjacent small chambers in the commodity housing chamber 4 are surely shielded for all time without producing the convection of cooled air and heated air.
