PROBLEM TO BE SOLVED: To provide an automatic vending machine which has a heat insulating diaphragm that is lighter than the conventional one and can be easily recycled and also has a commodity storage box that is internally divided by the heat insulating diaphragm into a cooling room and a heating room. SOLUTION: The primary part of a heat insulating diaphragm 18 of this automatic vending machine consists of an urethane foam board 19 and needs no metallic box that is used to the diaphragm of a conventional vending machine. Thereby the diaphragm 18 is lighter than the conventional one. The board 19 constructing the diaphragm 18, a guide member 20 and a deformation preventing member 22 are adhered and fixed to each other, and the member 20 is adhered and fixed to an airtight packing 21. However, the diaphragm 18 can be easily separated into its component members compared with the diaphragm of the conventional vending machine where the urethane foam is firmly unified with a metalic box as long as an adhesive having the proper adhesive strength is used. As a result, the diaphragm 18 can be easily recycled compared with the conventional one.
