PROBLEM TO BE SOLVED: To provide a linear motion guide unit in which the manufacturing costs are reduced and a lubrication maintenance free period is further extended by disposing a pipe forming an oil storage chamber in a holding plate.SOLUTION: A pipe 7 for holding a holding plate 6 on a casing 3 is disposed in the holding plate 6, and both end parts 69 of the pipe 7 are supported by an end cap 4. In the pipe 7, an oil storage chamber 55 which stores a lubrication oil in a hollow part is formed. Both end parts 69 of the oil storage chamber 55 communicate with the oil storage plate 10 and the lubrication oil in the oil storage chamber 55 may flow to the oil storage plate 10. A passing hole 9 extending in a longitudinal direction for fitting the pipe 7 is formed at the holding plate 6. Protruding part 27 for the pipe, in which the end parts 69 of the pipe 7 fit, are formed at the oil storage plate 10. |
