PROBLEM TO BE SOLVED: To allow a longitudinal deviation by correcting a deflection in a middle retaining portion, 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 51 projected from a position corresponding to a portion between upper and lower raceway surfaces 26 of a slider body 21 toward a guide rail 1 is formed in a return guide 5 which is a member to form the inner peripheral surface of a direction changing path in an attached state. A long hole 7 into which the projection 51 of the return guide 5 is fitted is formed in a longitudinal end of the middle retaining portion 4C of the retainer 4. An upper groove 8 into which a tip pawl part 44 of the upper side retaining portion 4A is fitted and a lower groove 9 into which the tip pawl part 44 of the lower side retaining portion 4B is fitted are formed in the end cap 22. The projection 51 of the return guide 5 is fitted into the long hole 7 of the retainer 4. The tip pawl 44 of the upper side retainer portion 4A is fitted into the upper groove 8 of the end cap 22. The tip pawl 44 of the lower side retaining portion 4B is fitted into the lower groove 9. COPYRIGHT: (C)2009,JPO&INPIT
