摘要： A linear motion guide unit has sleeves which form return passages and are formed of a high temperature resistant resin material which allows use in a high temperature environment. In the linear motion guide unit, spaces serving as grease pools are formed in the sleeves inserted into insertion holes of a carriage. The sleeves are formed of a thermoplastic resin whose heat distortion temperature is higher than 80° C. Each sleeve is formed by combining split circular members obtained by dividing a cylindrical member into two pieces along the longitudinal direction, and a plurality of grooves which become spaces are formed on the inner circumferential surfaces of the sprit circular members through cutting orthogonal to a parting plane between the split circular members.
