A motion guide device, comprising:

• a track member in which a rolling member rolling surface is formed along a longitudinal direction thereof;
• a movable member which is assembled to the track member to be reciprocally movable with a number of rolling members being interposed therebetween and which is provided with a loaded rolling member rolling surface constituting a loaded rolling member rolling path opposing to the rolling member rolling surface and a rolling member return path;
• a lid member provided with a pair of direction changing paths for connecting both end portions of the loaded rolling member rolling path and the rolling member return path to thereby constitute an endless circulation path;
• and
• flange portions formed to both end portions of the movable member in the reciprocally moving direction by means of insert molding,
• wherein the flange portions are provided with fitting portions formed to end portion sides of the movable member, and at least inner periphery surface side direction changing members of the direction changing paths are assembled to the fitting portions.
