<P>PROBLEM TO BE SOLVED: To provide a safe and inexpensive car wash by using rotation of a water turbine by water pressure as a driving source, and by discharging subsequent drain water to a car washing brush to wash a car. Ž<P>SOLUTION: The car wash includes the car washing brush 16 rotatably journaled thereto, and the driving part 2 for driving the rotation of the car washing brush 16. In the driving part 2, the water turbine 21 which is rotated in a turbine case 7 with a water amount supplied to the turbine case 7 and water pressure, is connected to a speed reducer 6 which converts the rotation of the water turbine 21 into driving rotation via an input shaft 20, as the driving source for driving the rotation of the car washing brush 16 journaled to the speed reducer 6. Thus, the water amount drained from the turbine case 7 is discharged to the car washing brush 16 to wash a vehicle C along its outer periphery while being moved. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
