Abstract: A miniature linear guideway includes a rail, a slider, two circulation fittings and a retainer. The slider and the circulation fitting are set on the rail, so that a circulation channel is formed between the rail and the slider for the balls to run. The circulation fitting has several turning convex portions. The retainer has a plate portion and two retaining portions. The two ends of each retaining portion are connected to the plate portion by a positioning portion, and the plate portion is adjacent to the slider. The positioning portions of the retainer abut the turning convex portions. The width of the plate portion of the retainer is smaller than the distance between the turning convex portions of the circulation fitting. Thereby, the miniature linear guideway of the present invention can optimize the assembly efficiency, thereby realizing the purpose of automatic assembly.
