  • Patent number: 9581204
    Abstract: A magnetic-scale-equipped motion guide apparatus is provided which can scrape iron powder adhered to a magnetic scale by a scraper or seal of a movable member without inviting adverse effects such as wearing away and deformation of the magnetic scale. The magnetic-scale-equipped motion guide apparatus of the present invention comprises a track member 1 having a rolling element rolling portion 1b and also an upper surface where through holes 18 into which fastening members are inserted open, a movable member 2 movably assembled to the track member 1 via a plurality of rolling elements 3, a groove 1a formed in the track member 1 and extended in a longitudinal direction, a magnetic scale 7 accommodated in the groove 1a and having north and south poles alternately formed in the longitudinal direction, and a cover member 8 that covers the magnetic scale 7 and also the through holes 18 of the track member 1.
