PROBLEM TO BE SOLVED: To provide a linear motion guiding device capable of smoothly running a slider on a guide rail with low noise by preventing the fall of rollers or a direct contact between the rollers forming rolling elements. SOLUTION: In this linear motion guiding device in which the slider moves relative to the guide rail through the rolling and moving of the rollers 46, a separator 50 is installed between the rollers 46, the rollers 46 are rotatably held between the roller holding projections 58 of an arm part 52 extended from the separator 50, and a guide projection 60 is formed on the center axis of the rollers 46 and on the outside of the arm part 52. The guide projection 60 is engaged with an guide groove formed in the endless circulation circuit of the slider, and the separator 50 is guided in the endless circulation circuit along the guide groove.
