PROBLEM TO BE SOLVED: To provide a linear motion guide unit capable of fixing an assembly of each member in a fitting type by reducing the number of parts to mount on a casing so as to correspond to miniaturization. SOLUTION: A slider 2 is constituted of a casing 3 on an inside surface 34 of which a track groove 13 is formed and on an outside surface 24 of which a recessed groove 21 and a return passage groove 18 are formed, an end cap 4 with a directional changing passage 14 arranged on both end surfaces 35 of the casing 3 formed on it and a frame type case 5 having a side plate part 22 facing the outside surface 24 of the casing 3 and an end plate part 23 facing an outer end surface 25. of the end cap 4. A protruded part 20 to be engaged with a recessed groove 21 is provided on an inside surface 36 of the side plate part 22, and the casing 3, the end cap 4 and the frame type case 5 are integrally fixed with each other by engaging the protruded part 20 with the recessed groove 21 by arranging the end cap 4 on the frame type case 5.
