PROBLEM TO BE SOLVED: To provide a motion guide device capabnle of easily attaching a cover for covering an upper surface of a track member and capable of preventing plastic deformation of the cover. SOLUTION: In this motion guide device 10 having the track member 11 having an opening existing on an upper surface 11a, a moving body 12 installed on the track member 11 in a state relatively movable in the lengthwise direction and the cover 14 for covering the upper surface 11a of the track member 11 over the width directional whole area, undercut parts 11e, lie recessed on the width directional central side are formed in a side edge part on the side for crossing the upper surface 11a of both side surfaces 11c, 11c of the track member 11. Engaging parts 14b, 14b for engaging with the undercut parts 11e of the track member 11 are formed on the width directional both ends of the cover 14 so as to sandwich the track member 11 in the width direction. The tips 14d of the respective engaging parts 14b are formed in the shape of opening to the width directional outside more than an intermediate part 14c of the engaging parts 14b for entering the undercut parts 11e. |
