A motion guide device (10) generally comprises a track member (11) having a horizontal surface (11a) and two side surfaces (11c) continuous to the horizontal surface, a movable member (12) mounted to the track member to be relatively movable with respect to the track member along a longitudinal direction thereof, and a cover member (14) covering the horizontal surface of the track member along an entire width direction thereof. The track member is formed with undercut portions (11e) formed to side edge portions of the side surfaces of the track member on the horizontal surface sides, and the undercut portions are recessed towards a central side of the track member in the width direction thereof. The cover member comprises a central flat portion and engaging portions formed at both end portions in the width direction thereof to be engaged with the undercut portions, respectively, so as to clamp the track member therebetween in the width direction. Each of the engaging portions comprises an intermediate section to be engaged with the undercut portion of the track member and a front end section bent outward from the intermediate section so as to be opened outward in the width direction of the track member. |
