PURPOSE:To simplify the washing of a large-sized vehicle and to improve the working efficiency of the washing, by mounting jet nozzles that can jet washing water against the front or rear of the vehicle. CONSTITUTION:By switching a switch ON, a pump and a motor 13 are rotated, and the washing water in a water storage tank is pumped up to be fed to first and second water supply pipes 2a, 2b. First and second jetting pipes 3a, 3 are swung by the rotation of the motor 13 via a supply 13a, a chain 19, a rotating crank 14, first and second connecting rods 15a, 15b and swinging links 16. Further, the wash water is jetted against the front and rear of the vehicle from V-shaped nozzles 4b attached to the forward and rearward ends of the second jetting pipes 3b. |
