CAR WASHER

PROBLEM TO BE SOLVED: To prevent the failure of the carrying on the brake, by driving a moving device when it detects that a car is located on a standby position, and stopping the moving device, and informing the guide relating to the carrying, when a car body is not detected under a condition that a detecting roller reaches an adequate position. SOLUTION: A roller 11a reaches a position P1 separated from a photoelectric switch 10 by a distance L, when the carrying of a car A2 is failed, that is, the car A1 is not normally moved because of the breaking or the like, after the carrying of the car A2 is started, and the roller 11a is passed under a front wheel TF. On this occasion, the photoelectric switch 10 does not detect the body of the car A2, whereby a car washer detects that the carrying is not normally performed, and stops the driving of a motor for driving a conveyer, to stop the conveyer 2. Then the guide that 'the car is not carried', is output by voice from a speaker as an informing means mounted on a car wash demand operating unit 33. An user can wash the car in safety at rest.
