The rotating shaft 6 is disposed at two positions on the left and right sides of the housing 7, and the plurality of rotating gears 8 are provided symmetrically about the rotating motor 5. Each rotating shaft 6 has a drive base 9 which is circular and rotates together with the rotating shaft 6 at the lower part thereof.
[0017]
The cleaning brush 3 is formed in a horizontally long shape, and both ends of the cleaning brush 3 are bridged and supported between the drive bases 9 of the rotating shaft 6. The cleaning brush 3 includes a base portion 11 formed in a horizontally long rectangle, and a brush portion 12 attached below the base portion.
[0018]
The brush portion 12 is composed of three rows of brushes 12a, 12b, and 12c arranged in the front-rear direction (the left-right direction in FIGS. 3 and 4), and the front-end brush 12a has a tip portion 14 extending forward. Further, it is inclined. The front end portion 14 of the brush 12a extending forward protrudes to the front outer side below the housing 7 when the moving cleaning brush 3 is positioned at the front end portion.
[0019]
In addition, the left and right ends of each brush 12a, 12b, 12c are formed to be inclined so that the tip portion 15 extends outward in the left-right direction. The tip portions 15 of the brushes 12a, 12b, and 12c extending to the left and right sides extend to the left and right sides below the housing 7 when the moving cleaning brush 3 is positioned at both the left and right ends. .
[0020]
The left and right ends of the brush 12a in the foremost row are formed so as to incline both forward and left and right outside, and when the cleaning brush 3 moves, the tip of the brush 12a passes outside the both ends of the front side of the housing 7. (See FIG. 1).
