When getting into the tire guide 17, the front tires and the rear tires of the vehicle 11 are located in different sections of the tire guide 17, respectively. A ten-key switch 18 is provided on the operation surface 7 in order to input the position of the tire to the control device 1 by the section number.

Further, the drive system 10 is provided with a tire wax solenoid 19 which supplies pressurized wax to the tire wax nozzle 16 by opening and closing a valve, and the sensor system 8 is further provided with a traveling device 9, for example, a traveling motor. An attached pulse generator 20 is provided and outputs a pulse to the control device 3 when the car wash machine body 3 travels by the travel device 9.

 In FIG. 1, reference numeral 21 denotes a power source of the control device 1.

The operation of the control device 1 having the above-described structure for hooking tires will be described with reference to the flowchart of FIG.

In the storage unit 6 of the control device 1, the distance from the position of the tire wax nozzle 16 to the center of each section of the tire guide 17 when the car wash main body 1 is at the stop position, and the pulse count number of the pulse generator 20 are stored. It is stored in advance.

First, confirm that the tire waxing mode is input (step F-1). If it is not the tire waxing mode, end the process. If it is the tire waxing mode, specify the number of the section of the tire position of the front wheel. Is input (step F-2), the count number from the input partition number to the tire position of the front wheel is searched (step F-3), and the partition number of the tire position of the rear wheel is input.
