PROBLEM TO BE SOLVED: To provide a car washing machine capable of suppressing the consumption of a liquid detergent to the necessary minimum and saving the labor of the operator. SOLUTION: When the car wash course is selected with the detergent to be sprayed in this car washing machine, the detergent pump-up stopping position as position where pumping-up of the detergent by a detergent pump is stopped, is set in front of the advance limit position so as not to cause the detergent to stagnate in an arch-shaped nozzle frame 7 when a runner 6 (arch-shaped nozzle frame 7) has reached the advance limit position. Accordingly when the advance limit position is reached, no detergent will remain in the arch-shaped nozzle frame 7, to allow avoiding a consumption of the detergent more than necessary, and it is possible to suppress the consumption of the detergent to the necessary minimum.
