PROBLEM TO BE SOLVED: To provide a motion guide device for actualizing further smooth circulation of rolling elements by reducing the interference of a band-shaped retainer with the outer peripheral wall of an infinite circuit.SOLUTION: A motion guide device 10 includes a raceway member 11 having a rolling element rolling surface 15 in the longitudinal direction, a moving member 13 movably installed on the raceway member 11 via a plurality of rolling elements 12, and a band-shaped retainer 30 having a plurality of rolling element storage parts in which the rolling elements 12 are individually stored, and formed in such an ended shape that the rolling elements 12 are stored in the rolling element storage parts and aligned as a rolling element train in the direction of arrangement in the infinite circuit. A pair of opposed ends 35, 35' of the band-shaped retainer 30 are formed with their phases shifted to each other in the inside direction of a direction change path 20. |
