PROBLEM TO BE SOLVED: To provide a linear motion rolling unit which achieves lubrication maintenance-free by making a spacer, which forms an end cap, with a porous molded body impregnated with lubricant to surely and stably feed a lubricant to balls, which roll on a turnaround path, from the porous molded body of the spacer.SOLUTION: The spacer 6 made of the porous molded body is arranged in a recessed part 16 of an end cap body 5. The spacer 6 consists of a storage part 31, linkage parts integrally constructed on both sides of the storage part 31, and lead-out parts integrated with the linkage parts and forming inner peripheral parts 29 of the turnaround path. When the balls roll on the turnaround path, the balls come into contact with the lead-out part of the porous molded body 7, and the lubricant impregnated the porous molded body is fed to the balls. |
