Abstract
A motion guide device including a hollow track base that has a rolling element rolling face formed along a longitudinal direction and has a hollow portion formed to be substantially rectangular in section along the longitudinal direction, and a moving member that has a load rolling element rolling face formed in a position facing the rolling element rolling face, the moving member being assembled movably in the longitudinal direction of the track base via a plurality of rolling elements between the rolling element rolling face and the load rolling element rolling face, wherein in the track base, a heat-treated region in which heat treatment is applied to a region including the rolling element rolling face and a non-heat-treated region to which heat treatment is not applied are formed in a section orthogonal to the longitudinal direction, and the heat-treated region is not superimposed on corner portions of the hollow portion.
