Motion guide device and method of assembling motion guide device

A motion guide device comprising:

• a raceway member having a rolling-element rolling groove formed thereon;
• a moving member body having a loaded rolling-element rolling groove formed facing the rolling-element rolling groove and having a non-loaded return path formed thereon;
• a cover member attached to each of both ends of the moving member body in a traveling direction thereof and having a direction changing path formed connecting the loaded rolling-element rolling groove and the non-loaded return path;
• a plurality of rolling elements accommodated in a rolling-element circulation path including the loaded rolling-element rolling groove of the moving member body;
• a damping plate, provided at the moving member body, having a surface facing a surface of the raceway member;
• a gap adjustment plate, provided at the moving member body, for adjusting a gap between the damping plate and the raceway member;
• a pair of holding plates attached to both ends of the moving member body in a traveling direction thereof;
• pressing means, provided at the moving member body, for pressing the gap adjustment plate against the holding plate in the traveling direction;
• and
• fixing means, provided at the moving member body, for fixing both the damping plate and the gap adjustment plate to the moving member body,
• wherein the moving member body and the gap adjustment plate have matching surfaces given gradients, respectively, and the gap between the damping plate and the raceway member is adjusted by moving the gap adjustment plate relative to the moving member body.
