A linear motion guide unit comprises a round track shaft and a slider surrounding around the track shaft for sliding movement along the track shaft. A lubricating plate assembly for self-lubrication may be simply installed in most prior linear motion guide units, with no need of modification in the basic specification of a slider. Both the lubricating plate assembly and the slider are held by a retaining ring in a radially enlarged bore in the housing of the instrument in such a manner as to be kept from falling off the bore. The lubricating plate assembly includes a case accommodating therein an end seal and a lubricant plate, which is composed of a lubricant- containing member, made of a sintered resinous component having a porous structure impregnated with lubricant. As the slider moves along the track shaft, the lubricant-containing member may apply incessantly the lubricant to the track shaft.
