Abstract
A linear motion guide unit track rail has lengthwise side surfaces with first and second raceway grooves in which a slider moves. Lubrication is provided in the slider for the raceway grooves of the track rail. The lubricator has a lubricant case. Lubricant delivery to the raceway grooves includes a head in sliding contact with the first raceway grooves and a leg, integral with the head, and extending through an opening into the case. The leg is inserted into the case through an elastic mouthpiece, and the head is elastically urged towards the raceway grooves of the track rail by the elastic mouthpiece.
