PROBLEM TO BE SOLVED: To provide a service wagon which can prevent mixing of a screw installing a duct panel into a food even if the screw comes loose and drops off. SOLUTION: The service wagon is formed with a hot storage compartment 1 and a cold storage compartment 2 to keep the food placed on the hot storage compartment 1 side of a tray 3 stored astride between the hot storage compartment 1 and the cold storage compartment 2 hot and to keep the food placed on the cold storage compartment 2 side cold. A mounting piece 5 folded on the back surface side is provided on the side end part of the duct panel 4. A screw inserting hole 6 is provided in a perforated manner on the mounting piece 5 and an operating hole 8 with larger radius than a screw head 7 is perforated in the duct panel 4 at a position that corresponds to the mounting piece 5. The duct panel 4 is mounted on the inner wall of each of the hot storage 1 and the cold storage compartment 2 by mounting the screw 9 inserted in the screw inserting hole 6 on a screw stopper 10 mounted on the inner wall of each of the hot storage compartment 1 and the cold storage compartment 2 to form a duct space 11 on the back surface side of the duct panel 4 which supplies warm air into the hot storage compartment 1 and cool air into the cold storage compartment 2.
