PURPOSE: A linear motion guide unit is provided to effectively prevent location changes due to a sliding motion of a roller cage assembly between a first guide rail and a second guide rail. CONSTITUTION: Rail units(115, 125) are formed into a concave shape of a V-shaped cross section. A first guide rail and a second guide rail(120) comprise the rail units. Roller cage assembly(130) is located between the first guide rail and the second guide rail. A plurality of roller installation cavities respectively restricts the movement of a roller which can be rotated. A cage board(145) is located between the first guide rail and the second guide rail. A pinion is installed at the cage board which can be rotated. One side of the pinion is connected with the first guide rail and the other side of the pinion is connected with the second guide rail. |
