The number of sequences is not limited. The brush 50 rotates in the direction of the arrow in FIG. 1, but the direction of rotation is not limited to this. That is, the direction may be opposite to the direction of the arrow, or both brushes 5
0 and 50 may be in the same direction (right or left direction).

A cloth wiping roll 52 is rotatably provided at the rearmost position. The cleaning brush 50 and the wiping roll 52 are linked by a motor 60 and a pulley transmission 61, and the transmission 61 is covered with a cover 62. In order to reliably clean the top surface of the sign pole 1, upper left and right guide plates 31, 3 are provided.
An auxiliary cleaning brush 53 that rotates around a horizontal axis may be provided between the two. A lock wire 56 may be connected to the parallel link mechanism 12 so as to be lockable by the lever 55 in the driver's seat, and may be locked when the cleaning device C is at a preferable position with respect to the marker pole 1. This lock may be performed before cleaning.

In cleaning, the driver controls the light four-wheeled vehicle 2 so as to be in front of the sign pole 1 by using the reference bar 5. When the light four-wheeled vehicle 2 travels, the cleaning device C receives a traveling resistance or the like. The resistance is controlled by springs (with a spring force control mechanism) 13 and 14 and is maintained as shown in FIG. Although traveling as it is, the cleaning device C can always travel in the front-rear direction by the parallel link mechanism 12 and can travel.

Since the distance to the marker pole 1 is confirmed by the reference bar 5, when the vehicle runs, the marker pole 1 is guided so as to be located between the left and right guide plates 31,31. Note that the water injection may be stopped before the guidance. Further, air injection, brush driving, and the like may be stopped. The sensor is activated by this guidance and passage,
It is also possible to freely configure so that all the injections / drives start / stop automatically.

The marking pole 1 is first cleaned of sand and the like by jetting air, and then cleaned by the next brush 50 by jetting water. Then, the moisture is wiped off by the last roll 52, thereby making it difficult to adhere dust and the like later.

At least one of the light four-wheeled vehicle 2 and the cleaning device C is provided with a sign plate under construction for safety. The traveling frame 17 is provided with a water supply tank 21 so that stable traveling can be performed. However, a compressor, a pump, and the like can be appropriately mounted. Further, the cleaning brush 50 may be configured to be detachable so that maintenance can be performed. Also, as a simple type,
It is also possible to directly attach the tip of the parallel link mechanism 12 to the main body frame 30. Further, as shown in FIG. 3, a resin cap 63 made of nylon or the like may be attached to the lower end of the rotating shaft of the cleaning brush 50 or the wiping roll 52 in order to prevent damage to the road surface. Although it is an additional example different from the above-described embodiment, a cleaning device for a side wall of a highway may be configured by a configuration in which the right side of the guide plate 31 and the nozzles and brushes attached thereto are omitted. It is.
