Abstract
A linear guide device with which it is possible to prevent leakage of lubricant introduced into a slider and thereby reduce an amount of lubricant consumed and to surely lubricate rolling elements and an endless circulation passage thereof, and with which furthermore this can be achieved by means of a simple construction. According to the invention, in a linear guide device made up of a track rail having a rolling surface of rolling elements and a slider which has a load rolling surface facing the rolling surface of the track rail with the rolling elements therebetween and a rolling element return passage parallel with this load rolling surface and has arcuate direction-reversing passages for guiding rolling elements between the load rolling surface and the rolling element return passage and can move along the track rail as the rolling elements circulate endlessly, a lubricant supply hole connecting with one of the direction-reversing passages is provided in at least one or the other of front and rear end faces of the slider and the end face in which this lubricant supply hole is provided is covered with a platelike member and a lubricant supply groove connecting with the lubricant…
