Wherein, the inner edge of the inner scraping brush 162 abuts against the rail 200 without a gap, and the width of the inner edge of the inner scraping brush 162 is preferably less than 50% of the thickness of the sheet body 161, so that the sheet body 161 can be formed with the inner scraper brush 162 and the outer scraper brush 163 in a preferred arrangement.

Part of the outer scraping brush 163 (eg, the following contact portion 1631) protrudes from the outer surface 1612 of the sheet body 161, and abuts against the part of the outer scraping brush 163 on the rail 200 without gaps (eg: The inner edge of the contact portion 1631 described below) is separated from the inner surface 1611 of the sheet body 161 by a distance greater than the distance between the outer surface 1612 and the inner surface 1611 of the sheet body 161 (that is, the thickness of the sheet body 161 ).

Further, in this embodiment, the outer wiper 163 includes a contact portion 1631 that abuts on the rail 200 without a gap, and an arm portion 1632 connecting the contact portion 1631 and the inner wiper 162, and the The contact portion 1631 can swing relative to the inner wiper 162 via the arm portion 1632 described above. That is to say, the inner edge of the inner wiper 162 and the inner edge of the contact portion 1631 of the outer wiper 163 are spaced apart from each other to abut on the rail 200 without any gap. It should be noted that the outer wiper 163 of this embodiment has a cantilever function compared to the inner wiper 162, so that the outer wiper 163 can form a better dustproof effect on the rail 200. Accordingly, the outer scraper brush 163 of this embodiment preferably excludes any scraper brushes that do not have a cantilever function, and the two scraper brushes 162, 163 of this embodiment preferably exclude two brushes having the same structure.

In addition, the sheet body 161 can be concavely formed with an outer groove 1613 surrounding the outer wiper 163 from its outer surface 1612, and the depth of the outer groove 1613 is not greater than the outer surface of the above-mentioned sheet body 161 The distance between 1612 and the inner surface 1611 (that is, the thickness of the sheet body 161) is 50%. Accordingly, the dust-proof oil seal sheet 16 passes through the outer groove 1613 formed in the sheet body 161, so that the contact portion 1631 of the outer wiper brush 163 can form a better swinging effect relative to the inner wiper brush 162.
