Abstract
The linear motion guide unit has the lubricating means that is easy to be handled, attached to and detached from the track rail by means of supporting a lubricant plate in a holder. The lubricating means has a lubricant plate divided into a pair of lubricant plate components disposed in symmetry with each other, and the holder of a frame surrounding the lubricant plate components to keep steadily the components. The lubricant plate components each have a protrusion which move in sliding contact with raceway grooves of the track rail so as to feed lubricant to the raceway grooves. The lubricant plate components have protrusions fitted into windows in the holder. A pair of the lubricant plate components is supported in such a manner that they are separated by a center wall extending at an upper section of the holder towards the track rail.
