PROBLEM TO BE SOLVED: To sufficiently and reliably secure heat insulating performance without bringing a problem owing to interference with another component, and complexity in a production work or a recycling work. SOLUTION: Heat insulating sheets 70 are arranged on the internal wall surface of a storage area for storing merchandises in a vending machine. Notches 81 are respectively provided in wall members 12b, 12d, 16b, 17b constituting the internal wall surface of the storage area, and, then, tongue pieces 80 are constituted along the wall members 12b, 12d, 16b, 17b in the extending directions. Through-holes 71 are formed in the heat insulating sheets 70, and the tongue pieces 80 are put through the holes 71. Thus, the heat insulating sheets 70 are held on the internal wall surface of the storage area. COPYRIGHT: (C)2004,JPO
