The germicidal air is circulated in the storage 10. Therefore, even when food or the like to which bacteria have adhered is stored in the serving car, it operates according to the time set in the timekeeping control means 32 which has set the time period in which the serving has been completed, and the inside of the vehicle body Can be sterilized with sterilizing air, and it becomes a serving truck with excellent antibacterial properties. In addition, sterilization can be performed by selecting a time period when the catering car is not used, so sterilization with excellent safety for workers can be performed, and sterilization can be performed after serving is completed, so it is stored in the catering car. This has little effect on the food that is to be sterilized, and sterilization that is excellent in food safety is possible. Also,
Even if the worker does not perform the sterilization start operation every day, the processing can be performed every day and the operability is excellent.

The disinfecting means 30 is not limited to being provided in the hot air duct 11, and the electric opening / closing means 31 or the timing control means 32 controls the cooling air circulating fan 27.
May be provided in the cool air duct 21, and the hot air circulation fan 1 may be provided in the cool air duct 21.
When both the operation of the fan 7 and the cool air circulation fan 27 are formed so as to be controllable, they may be provided at any positions on the vehicle body 1. The inside of the hot air duct 11 or the cold air duct 2
1 is preferable because sterilizing air can be reliably circulated throughout the vehicle body.

An opening / closing detecting means 33 for detecting the presence or absence of a door provided at an opening on the side surface of the vehicle body 1 is provided near the door, and when the opening is open, the operation of the sterilizing means 30 is performed. Is preferably stopped. In this case, if the door is opened by mistake while germicidal air is circulated in the vehicle body 1, outflow of the germicidal air can be minimized.

As the sterilizing air, ozone is generally used, but it is not particularly limited, and any air can be used as long as it has no effect when serving food and can be sterilized. In addition, the sterilizing means 30 is not limited to a device that creates sterilizing air, and may include a gas outlet connected to a gas cylinder that sends out sterilizing air. The amount of sterilizing air generated is appropriately adjusted according to the volume in the vehicle body 1, the processing time, and the like.
