Further, the scraping device 12 is assembled to the outer end surfaces of both end covers 13 of the slider 14 with a plurality of screws G, and the scraping device 12 is displaced by the slider 14 and the slide way 11 reciprocatingly moving. At this time, dust or foreign matter on the slide way 11 is scraped in advance, and dust and foreign matter enter through the both end covers 13 to enter the slider 14 and circulate and recirculate between the slider 14 and both end covers 13 (see FIG. (Not shown) is capable of preventing the rotation and displacement of the dust from coming into contact with the dust. However, such a prior art design causes the following problems.

1. It takes time to install the scraping device.
2. Since this scraper device loses its effect due to damage or fatigue due to long-term use, such a design is difficult for the user to remove, and dust or other contaminants are difficult to remove from the slider. The service life of the linear slider is reduced by easily scratching the rotating road surface.

  In order to solve the above-mentioned problems, a scrap scraper such as US Pat. No. 6,106,154 has been actively researched and developed in the industry. The detailed structure will be described as follows.

As the contents of the application are referred to, the scraping device is provided with a plurality of through holes, and the outside of the end cover is provided with a rib with respect to the through holes. By combining the through holes and the ribs (matching by the locking method), the scraping device is fixed on the end cover, and the function of being quickly attached can be achieved. However, when removing the scraping device, it is not only necessary to separate the plurality of ribs and through-holes at the same time, but also because the tool cannot be removed without the aid of a tool. There is a need to.
