In particular, according to the present embodiment, since the coil spring 40 is provided between the abutting block 38 of the abutting member 34 and the fixing portion 36, the end surface of the steel plate 12 is abutted to the abutting surface 38A of the abutting block 38. It is possible to soften the impact when hitting against.

Further, according to the present embodiment, since the hair shaping member 42 is provided on the outer peripheral portion of the contact surface 38A of the abutting block 38, the hair shaping member 42 regulates the flow of the brush hair 52 of the brush roll 48. Can be done.

Specifically, as shown in FIG. 10, the axial length L1 of the brush roll 48 is made larger than the width L2 of the steel plate 12. Therefore, when the steel plate 12 is cleaned by the brush roll 48, the brush bristles 52 at the axial end of the brush roll 48 may come into contact with the contact member 34 and the brush bristles 52 may scatter.

At this time, since the hair shaping member 42 extends obliquely outward from the outer peripheral portion of the contact surface 38A of the abutting block 38, the scattered brush hairs 52 are arranged along the hair shaping member 42, so that the brush hairs are arranged. The variation of 52 is suppressed. As a result, it is possible to prevent the brush bristles 52 of the brush roll 48 from being scattered and the cleaning efficiency of the steel plate 12 from being lowered.

(Other embodiments)
Although an example of an embodiment of the present invention has been described, the present invention is not limited to such an embodiment, and various other embodiments are possible within the scope of the present invention.

For example, in the above embodiment, the frame unit 16 is provided with a pair of brush rolls 48, an upper brush roll 48A and a lower brush roll 48B. However, one brush roll may be provided only on either the upper side or the lower side of the frame unit 16, and one side of the steel plate 12 may be cleaned by this one brush roll.

Further, an injection device (not shown) may be provided in the frame unit 16 to inject low-pressure water onto the steel plate 12 from which dirt such as mud has been scraped off by the injection device. By using the cleaning with the brush roll 48 and the injection of low-pressure water in combination, the cleaning ability of the steel sheet 12 can be further enhanced and the diffusion of dust and the like can be suppressed.

In addition, the frame unit 16 may be provided with a blower (not shown) that blows wind. By blowing wind on the steel sheet 12 with a blower, dirt such as mud scraped from the steel sheet 12 can be blown off in a predetermined direction, and the cleaning ability of the steel sheet 12 can be further enhanced.
