Thus, the above-described rolling movement is applied to the brush plate 7.

The truck wheel washer 2 is arranged such that the upper surface of a snowboard 5 provided on the upper part of the water storage tank 3 is substantially flush with the floor surface. It is possible to pass over the snowboard 5 smoothly. In the case shown in the figure, the opening of the saw 5 is long in the direction of passage of the truck A, and the width thereof is smaller than the width of the wheels C of the truck A. I have to.

In the case shown in the figure, the water storage tank 3 is formed in a horizontally long rectangular shape corresponding to the width of the bogie A, and the snowboard 5 is horizontally fixed to substantially the entire upper surface inside the water tank 3. In this example, the brush plates 7 are arranged at the positions indicated by the arrows, and the brush plates 7 are separately driven by driving means 8 arranged outside both sides of the water tank 3.

As shown in FIG. 5, on the upper surface of the brush plate 7,
A brush 11 that fits in the opening of the saw blade 5 is implanted such that the upper end thereof protrudes upward from the upper surface of the saw blade 5 by a predetermined length. The rolling movement is performed within the opening 5.

Further, as shown in FIG. 5, the water storage tank 3
The water level of the stored cleaning liquid D is set so that the lower half of the brush 11 is immersed in the cleaning liquid D, and the upper part of the brush 11 is drawn into the cleaning liquid D by a capillary phenomenon so as to be in a wet state. As a matter of course, the water level of the cleaning liquid D is set below the upper surface of the saw blade 5. Also,
The brush 11 is provided by bundling a large number of hairs on the upper surface of the brush plate 7 so as to be scattered, and is made of a material in which a lower part of the washing liquid D is immersed in a capillary. What is sucked up by the phenomenon may be selected and used.

The water reservoir 3 has a water inlet 12 and a drain 13 for the cleaning liquid D. As shown in FIG. 3, the peripheral walls on both sides are slightly lower than the front and rear peripheral walls.
