The present invention provides a linear guide apparatus comprising an axially extending guide rail having axial rolling member receiving grooves formed in both side surfaces thereof, a slider mounted on the guide rail and having load rolling member movement grooves opposed to the rolling member receiving grooves, and a number of rolling members inserted between the rolling member receiving grooves and the load rolling movement grooves and adapted to shift the slider along the rail by rolling movements. The slider comprises a slider body in which the load rolling movement grooves are formed in inner surfaces of a pair of skirt portions of the slider body, and rolling member returning passages parallel with the load rolling movement grooves are formed in the skirt portions. A pair of end caps each having arcuate passages connecting the load rolling movement grooves and the corresponding rolling member returning passages are secured to respective end surfaces of the slider body. Further an easily and elastically deformable thin coating layer made of elastomer material is formed on a surface of the slider body.
