Provided is a motion guide apparatus including a track member with a rolling-element rolling surface and a moving member with a load rolling-element rolling surface, the moving member being movably assembled to the track member via a rolling element provided between the moving member and the track member, wherein: the cross-sectional shape of each of the rolling-element rolling and the load rolling-element rolling surfaces has a circular arc shape projecting in the direction that the rolling-element rolling surface and the load rolling-element rolling surface face each other; the rolling element has a drum-shaped cross-section with a diameter gradually reduced from both ends of the rolling element so as to correspond to the cross-sectional shape of the rolling-element rolling surface and the load rolling-element rolling surface; and the rolling-element rolling surface and the load rolling-element rolling surface configure an angular contact structure via the rolling element.
