A linear motion guide unit is provided with lubricating means that is compact in size and may continue to apply lubricant to raceway grooves on the track rail for a long service life. The lubricating means has a case containing therein lubricant and having an opening that is closed with a lubricating plate assembly for applying the lubricant onto the raceway grooves. A slider movable along the track rail has mounted at one end thereof with a case, made therein with a lubricant reservoir, by clamping bolts. The opening of the case is closed with the lubricating plate assembly composed of a lubricant-containing member of sintered porous resinous component, and a core metal for reinforcing the lubricant-containing member. The lubricant in the reservoir soaks into the lubricant-containing member and oozes onto the raceway grooves of the track rail through convexities of the lubricant-containing member, thereby lubricating the confronting raceway grooves of the track rail and the sliding element.
