A lubricant supplying unit preferable for a linear motion apparatus such as a linear guide unit and a ball screw unit, always capable of coating all rolling body rolling grooves formed on a track shaft with an equal amount of lubricant regardless of a difference in the mounting posture of the track shaft with respect to a fixing unit, is provided. A lubricant supplying system for achieving such an object comprises a casing fixed to the slide member, a plurality of coating pieces which are protruded from plural positions of the casing so that they are in contact with the track shaft for coating the track shaft with lubricant and a lubricant accommodating chamber provided in the casing for supplying lubricant to the coating piece, wherein the plurality of the coating pieces are divided to groups consisting of one or two or more adjacent coating pieces and the lubricant accommodating chambers is formed for each of the groups.
