PROBLEM TO BE SOLVED: To provide a service wagon which can be used while keeping the inside of a cooling chamber at a low temperature for a long period of time without enlarging a wagon main body. SOLUTION: This service wagon 1 is provided with a hand pushing type wagon body 2 having a plurality of wheels 5, and the inside of the cooling chamber 7 is cooled by a small-sized stirling refrigerator 15 driven by electric power from a secondary battery 25 which is a built-in power source housed in the battery chamber 9 of the wagon body 2 and capable of cooling to -18°C or lower by small power consumption. Thus, a mechanism for cooling and the secondary battery 25 loaded on the wagon body 2 are made to be small-sized, and the service wagon 1 capable of not only increasing the ratio of a shelf part 6 in the wagon body 2 and loading more merchandise but also moving for a long period of time while cooling the inside of the cooling chamber 7 by the stirling refrigerator 15 for sales aboard a train is obtained.
