<p>PROBLEM TO BE SOLVED: To provide a motion guide device which can secure a length of a moving member by employing the moving member of a normal length, can secure the number of rolling bodies which are loaded with loads, can make the rolling bodies load the loads even in any curved part, is suppressed in wobbling, and can perform a high-accuracy guide.SOLUTION: In a motion guide device 1 which comprises a raceway member 10 in which a rolling body rolling face 11 is formed along an extension direction, and a loaded rolling body rolling face which is formed while opposing the rolling body rolling face 11, the raceway member 10 comprises a linearly-extending linear part 12, and a curved part 13 which is curved at a prescribed curvature radius, the rolling body rolling face 11 includes a linear part rolling body rolling face formed in the linear part 12, and a curved part rolling body rolling face formed in the curved part 13, and the curved part rolling body rolling face has a first curved part rolling body rolling face having a width-expanded part which is mildly expanded in width from the linear part rolling body rolling face.</p> |
