The cable cleaner 330 is provided in the vicinity of the cable entrance on the side surface of the carriage 300, for example. The cable cleaning device 330 basically removes foreign matters attached to the power cable 140 when the power cable 140 drawn out from the cable reel 310 with the movement of the power supply device 280 is wound around the cable reel 310. .

  The cable cleaning device 330 has a brush for removing foreign substances attached to the power cable 140 (described later). If dirt accumulates in a specific portion of the brush, the power cable 140 may not be sufficiently cleaned. Therefore, in cable cleaning device 330 according to this embodiment, a brush is provided on the circumferential surface of the circular rotating body so as to be in sliding contact with power cable 140. The brush is formed so as to generate a rotational force on the rotating body as the power cable 140 moves. Hereinafter, the configuration of the cable cleaning device 330 will be described.

(Configuration of cable cleaner 330)
FIG. 5 is a diagram for conceptually explaining the configuration of the cable cleaning device 330 shown in FIG. 4. Referring to FIG. 5, the cable cleaning device 330 includes a rotating body 130. The rotating body 130 is formed in a circular shape, and a brush 132 is provided on the outer peripheral surface of the rotating body 130. The rotating body 130 is disposed such that the rotation axis is along the moving direction of the power cable 140, and the brush 132 provided on the outer peripheral surface is slidably contacted with the power cable 140.

  6 is a plan view of the rotating body 130 shown in FIG. 5 from the direction of the rotation axis. Referring to FIG. 6, brush 132 is provided uniformly (continuously and uniformly) in the rotation direction of rotating body 130 on the outer peripheral surface of rotating body 130. And the brush 132 is provided in the outer peripheral surface of the rotary body 130 so that the front-end | tip side of a brush may incline to one direction (counterclockwise direction in FIG. 6) of the rotation direction of the rotary body 130. FIG.

  In the drawing, the brush 132 is planted obliquely with respect to the outer circumferential surface of the rotating body 130. However, the brush is planted perpendicularly to the outer circumferential surface of the rotating body 130, and the tip of the brush is the rotating body. It is good also as a structure bent in one direction of 130 rotation directions.

  With such a configuration, a rotational force is applied to the rotating body 130 from the moving power cable 140 as the power cable 140 moves (FIG. 5). Specifically, with the movement of the power cable 140, the rotating body 130 is given a rotational force in a direction opposite to the direction in which the brush tip is inclined (the clockwise direction in FIG. 6). Thereby, it can avoid that only the specific location of the circumferential direction of the brush 132 contacts the power cable 140, and it can make it difficult to collect dirt at the specific location of the brush 132.

  Referring to FIG. 5 again, in this embodiment, cable cleaning device 330 includes a rotating body 134 on the opposite side of rotating body 130 with power cable 140 interposed therebetween.
