Abstract:
1. A guide apparatus, comprising: a track rail having rolling-element raceway surfaces formed along a longitudinal direction thereof, a moving block attached to the track rail by way of a plurality of rolling elements in a relatively-movable manner, the moving block having an end-face dustproof brush attached to an outside of each of the side covers with respect to the direction of relative movement, the end-face dustproof brush having a plurality of brush members whose tip end contacts a surface of the track rail and which eliminates extraneous matters adhering to the surface of the track rail, wherein the end-face dustproof brush has a casing and the plurality of brush members are provided in the casing while being separated from each other at a given interval with reference to the direction of relative movement, and wherein, of the plurality of brush members of the end-face dust proof brush, brush wires of a brush member located outside with reference to the direction of relative movement have a larger wire diameter, a higher hardness, and a lower arrangement density than brush wires of a brush member located inside with reference to the direction of relative movement.
