PROBLEM TO BE SOLVED: To prevent the leakage of refrigerant into a storage as a sealed space in a vending machine having a cooling system in which the combustible refrigerant is packed. SOLUTION: An evaporator 115 composed of one seamless pipe is mounted near a front part of the commodity storage 102, and a pipe connecting part can be easily arranged in a machine chamber 119 by means of a short pipe, so that a welded part does not exist in the commodity storage 102, and the leakage of the refrigerant into the commodity storage 102 caused by poor welding can be prevented.
