PROBLEM TO BE SOLVED: To provide a linear motion guide device capable of achieving a long service life by reducing the unsteady movement of rolling elements in a rolling element passage and improving positioning accuracy. SOLUTION: The linear motion guide device includes a guide rail, a slider, the rolling elements 6 inserted between rolling element rolling grooves formed in the guide rail and the slider respectively, and separators 10 holding the rolling elements 6. The rolling element 6 is formed with one or more groove parts 6b making a round of the peripheral surface along a rolling direction. The separator 10 includes a separator body 11 including an engaging part 11a engaged with the groove part 6b, and a connection part 12 connecting each separator body 11 along the peripheral surface of the rolling element 6.
