摘要： A guide apparatus including a track rail and a moving block is free from the possibility of foreign matter entering the moving block through the gaps between the side surfaces of the track rail and the inner side surfaces of the moving block even in an environment where many fine dust particles are flying. A guide apparatus has a track rail and a moving block 20 relatively movably attached to the track rail with rolling elements interposed therebetween. The rolling elements recirculate through rolling element recirculation passages. Foreign matter entry preventing plates 34 are provided so that their respective distal ends longitudinally contact the opposite side surfaces of the track rail to close the gaps between the side surfaces of the track rail and at least the inner side surfaces of skirt portions on both sides of a moving block body 21 and the inner side surfaces of end plates of the moving block 20.

摘要： In order to provide a long-life, highly-reliable guide apparatus which exhibits dustproof performance and prevents intrusion of dust into the moving block in environments where there are lots of fine dust such as gypsum and ceramic powder and where no oil contents or oil contents are not liked, there is provided a guide apparatus having a track rail 11, in which rolling-element raceway grooves 12-1 to 12-4 are formed along a longitudinal direction thereof, and a moving block 20 attached to the track rail by way of a plurality of rolling elements in a relatively-movable manner, wherein an end-face dustproof brush 25, which has a brush member 36 whose tip end contacts a surface of the track rail 11 and which eliminates extraneous matters adhering to-che surface of the track rail 11 by means of the brush member 36, is attached to outside of each of the side covers 22 with respect to the direction of relative movement.
