PROBLEM TO BE SOLVED: To reduce noise and to improve operability by securing stable revolving motion of separators including balls by preventing the falling of the separators, and to reduce the cost by remarkably shortening an assembling time. SOLUTION: This linear motion guide bearing device 30 is provided with the separators 50 respectively arranged between the balls 36 adjacent to each other. The separators 50 respectively have a separator main body 51 mounted between the balls 36 adjacent to each other, and arm parts 52 integrally mounted on end parts in the groove width direction of rolling element rolling grooves 33, 35 of the balls 36, of the separator main body 51, and guide grooves 55 are formed to guide the arm parts 52 of the separators along the circulating direction of the balls 36 in circulating the balls 36 on load raceways, direction turning passages and rolling element passages 38a.
