ABSTRACT:
A lubricating member is capable of being used in any type of linear motion rolling guide unit and of appropriately lubricating raceway faces over a long period. The lubricating member used in a linear motion rolling guide unit comprises a body4impregnated with a lubricant and being in contact with raceway faces of a rail to supply the lubricant to the raceway faces. The body4comprises either a single or a plurality of embedding portions8having either a recess or a hole. A saturation holding member9is embedded in the embedded portion8. The saturation holding member9holds a larger amount of lubricant per unit volume than the body4holds the amount of lubricant, and has a relationship ensuring that it has a force sucking the lubricant equal to or smaller than that the body4has.
