  At this time, for example, an uncleaned article T ′ made up of an electrical system such as an inverter device, a SIV circuit breaker, a heat insulating box, and a rectifier, various equipment and instruments belonging to a signal system is provided at the subsequent stage of the first cleaned article T. If there is, the turbofan T.W. from the slit 9 of the air ejection nozzle 10 of the air barrier ejection mechanism 11. Mixing in which the cleaning water W and the compressed air K injected from the cleaning water injection nozzle 5 and the cleaning water side injection nozzle 7 are mixed as described above when B is driven and the air K1 is injected. During the cleaning of the cleaning article T with the water W ′, the cleaning area S for cleaning the cleaning article T and the protection area N of the non-cleaning article T ′ are isolated. Therefore, the non-cleaning article T ′ made up of an electrical system such as an inverter device, SIV circuit breaker, circuit breaker box, rectifier, brake control device, etc. Therefore, there will be no short circuit, and there will be no breakdown or damage to equipment or equipment.

  In this way, the mixed water W ′ of the washing water W and the compressed air K is jetted from the washing water jet nozzle 5 in the first row and the washing water side jet nozzles 7, 7 and washed. One cleaning article T includes a cleaning water jet nozzle 5 provided in the second row when the vehicle 1 to be cleaned is pushed on the rails 2 and 2 at a predetermined speed by the guide wheel 21, and the cleaning water side portion.
