The second support plate 7 is located in the hollow portion of the annular base portion 5a of the rotary brush 5, and the outer peripheral portion of the support plate is fixed to the base portion to support the base portion. The rotary brush 5 has a brush planted on the front surface of a base portion 5a, so that the central portion of the brush is a hollow portion 5b.

In the structure of the rotary drive mechanism of the rotary shaft 3, as shown in FIG. 1, a spur gear 12 is fixed to the outer periphery of the rotary shaft 3, and the spur gear has an intermediate gear 13 for transmission shown in FIG. Mesh with each other, and the rotational force of the electric motor 14 is transmitted to this intermediate gear.

Therefore, when the electric motor 14 is driven, the rotational force is changed to the spur gear.
12, transmitted to the intermediate gear 13, and the rotating shaft 3 rotates, so that the rotating brush 5 is rotationally driven via the support portion 4.

Further, as shown in FIG. 1, a pressure water pipe 15 is piped through a bearing 16 at the axial center of the rotatable rotary shaft 3, and both ends of this pressure water pipe are outside the both ends of this rotation shaft. It projects toward. A joint body 17 is attached to the rear end portion (right end portion in FIG. 1) of the pressure water pipe 15, and this joint body is fixed to the base 1 by a rotation stop bolt 18. A front end of a high-pressure water hose (not shown) is connected to a connecting hole 17a of the joint body 17 through which the rear end of the pressurized water pipe 15 communicates. Also, a joint body 19 is attached to the tip of the pressure water pipe 15,
A nozzle 20 is provided in this joint body, and pressurized water is jetted from this nozzle toward the front wall surface 11 through the hollow portion 5a of the rotary brush 5.

Next, a brush cover for preventing water from scattering will be described. In this structure, a horizontal stay 21 is attached to the base 1, and the rotary brush 5 is attached to the tip of this horizontal stay.
