<P>PROBLEM TO BE SOLVED: To provide a vending machine in which cooling efficiency of a storage having an in-box heat radiator can be improved. Ž<P>SOLUTION: This vending machine 10 has: a first valve device V11 disposed between the in-box heat radiator 31 and a second box outside heat radiator 52, shutting off communication of a refrigerant between the in-box heat radiator 31 and the second box outside heat radiator 52 in time of cooling of the first storage 11; and a second valve device V12 disposed between a compressor 41 and the in-box heat radiator 31, forbidding a flow of the refrigerant from the in-box heat radiator 31 toward the compressor 41. Thereby, it is prevented that the refrigerant remaining inside the in-box heat radiator 31 flows out to a discharge side of the compressor 41, so that reduction of the cooling efficiency of the storage 11 capable of occurring by a re-inflow of the refrigerant warmed by the outflow into the in-box heat radiator 31 can be avoided.
