PROBLEM TO BE SOLVED: To provide a linear guide equipped with a rolling element-storing belt admitting easy installation of balls and capable of suppressing swings and the friction with a guide groove. SOLUTION: The linear guide 10 has rolling element storage parts 55 bounded by a plurality of spacer parts 51 and a coupling arm part 61, whereby balls 46 are stored in the respective rolling element storage parts 55 and put in alignment inside an endless circulation path 28, and is equipped with a rolling element-storing belt 50 where the coupling arm part 61 is guided by the guide groove formed in the endless circulation path 28, wherein the rolling element storage parts 55 admit falling-off of the balls 46 by at least either of the obverse-reverse directions, while the spacer parts positioned on a rolling element raceway 26 within the endless circulation path 28 comprise two types, a one having an outside abutting surface to abut to the balls 46 so that movement toward the inside surface of the endless circulation path 28 from the installed condition is not possible and another having an inside abutting surface to abut to the balls 46 so that movement toward the periphery of the endless circulation path 28 from the installed condition is not possible.
