PROBLEM TO BE SOLVED: To provide a motion guide device enabling smooth operation with simple configuration and with small travel sound of a movable body, even in a case where a curve part is included in a track body.SOLUTION: A motion guide device 1 has a track body 10 and a movable body 20 provided movably along the track body 10. The track body 10 has a groove part 13 formed along a longitudinal direction of the track body 10, and a plurality of rolling surfaces 14 formed inside and outside the groove part 13. The movable body 20 has a plurality of rotors 30 rolling on the plurality of rolling surfaces 14. All contacts 40 at which the plurality of rotors 30 contact with the plurality of rolling surfaces 14 are arranged on the same straight line L, on a cross section orthogonal to the longitudinal direction of the track body 10.SELECTED DRAWING: Figure 3 【課題】軌道体に曲線部が含まれている場合であっても、簡易的な構成で且つ移動体の走行音が小さく滑らかな動作が可能な運動案内装置及び搬送装置の提供。【解決手段】軌道体１０と、軌道体１０に沿って移動自在に設けられた移動体２０と、を有する運動案内装置１であって、軌道体１０は、軌道体１０の長手方向に沿って形成された溝部１３と、溝部１３の内外に形成された複数の転走面１４と、を有し、移動体２０は、複数の転走面１４を転走する複数の回転体３０を有し、複数の回転体３０が複数の転走面１４に接触するそれぞれの接点４０が、軌道体１０の長手方向と直交する断面において、同一直線Ｌ上に配置されている、という構成を採用する。【選択図】図３
