Motion guide apparatus

A motion guide apparatus comprising:

• a track member including a rolling element rolling surface;
• and
• a movable member configured to be assembled to the track member via a plurality of rolling elements in such a manner as to be movable, the movable member including:
• a movable member body having a loaded rolling element rolling surface facing the rolling element rolling surface of the track member, and a return path substantially parallel to the loaded rolling element rolling surface;
• and a lid member provided at an end of the movable member body, the lid member having a turn-around path connected to the loaded rolling element rolling surface and the return path of the movable member body, wherein
• a first inclined surface inclined relative to the loaded rolling element rolling surface is formed at an end of the loaded rolling element rolling surface of the movable member body,
• a second inclined surface inclined more than the first inclined surface is formed at an end of the first inclined surface, and
• L1≥1 Da, L2≥1 Da, and L1>L2 are set, where L1 is the length of the first inclined surface in a length direction of the loaded rolling element rolling surface of the movable member body, L2 is the length of the second inclined surface in the length direction, and Da is the diameter of the rolling element.
