PROBLEM TO BE SOLVED: To correct a deflection in a middle retaining portion and to permit a longitudinal deviation when attaching a retainer comprising an upper side retaining portion, a lower side retaining portion, and the middle retaining portion to an end cap. SOLUTION: A projection 5 is projected toward a guide rail 1 side in a position corresponding to a portion between upper and lower track surfaces 26 of a slider body 21 of the end cap 22. A long hole 7 into which the projection 5 of the end cap 22 is fitted is formed in a longitudinal end part of the middle retaining portion 4C of the retainer 4. An upper groove 8 and a lower groove 9 into which a tip pawl 44 of the upper side retaining portion 4A and a tip pawl 44 of the lower side retaining portion 4B are fitted are formed in the end cap 22. The projection 5 of the end cap 22 is fitted into the long hole 7 of the retainer 4. The tip pawl 44 of the upper retaining portion 4A is fitted into the upper groove 8 of the end cap 22.
