PROBLEM TO BE SOLVED: To provide a car washing machine with a simple and inexpensive constitution capable of shortening a time for filling a drained water supply hose with water until water injection is started, and sufficiently washing a car to an expected extent while reducing water consumption. SOLUTION: By the control of a motor driving means with a control means, a motor is rotated at a high speed H within a setting time I from a time when a water-feeding start signal ON<SB>1</SB>is turned on, and the motor is rotated normally at a lower speed L after a setting time has been elapsed O. By the high-speed rotation of the motor, the water can be fed to a water supply hose at a high speed (high pressure), the empty water supply hose can be filled with water for a short time so as to shorten a time until the water injection from a nozzle is started. In car washing, by the normal rotation of the motor, the water can be fed to the water supply hose at a low speed (low pressure) so as to inject the water toward a washed vehicle at a low speed, to reduce water consumption.
