CAR WASHING DEVICE

PROBLEM TO BE SOLVED: To avoid a car washing failure by detecting a vehicle in the entrance stand-by position of a car washing device, a position on a moving device of a roller and a body at the entrance of a device body, and detecting a vehicle shape from the moving position of the roller at the pressing starting time point of the roller and controlling to start washing even in the case of the vehicle not existing in the stand-by position after movement. SOLUTION: Even when an automobile A goes over a stop plate 17 and the front end of a body is detected by a photoelectric switch 10, a front wheel TF is deemed to be on a front vehicle detecting switch 18, and a vehicle shape is detected to start washing. The detected vehicle shape at this time is detected in such a way that the distance from the front wheel TF to the front end of the body is equal to the distance L2 between the vehicle detecting switch 18 and the photoelectric switch 10. The rear end position of a roof part can be detected without generating difference from the actual vehicle shape. Since a driver of the automobile A moves the automobile A into a position where a car wash demand unit 33 can be operated while staying in the automobile A, the distance between the vehicle detecting switch 18 and the front wheel TF is shortened, and an error is reduced. As a result, a car washing failure caused by the failure of entry can be prevented.
