Abstract
A motion guide device for preventing interference of belt members with guide grooves. The motion guide device includes an endless circulation path for rolling elements, and a coupling member received in the endless circulation path. The endless circulation path includes a load rolling element path, a rolling element return path, and a direction-changing path. The direction-changing path includes a guide groove for the coupling member, which has an outer circumferential guide surface and an inner circumferential guide surface. The guide groove has a maximum width at a midpoint of a path within a range of from a coupling end between the direction-changing path and the load rolling element path or the rolling element return path to a center portion of the direction-changing path, and the groove width at the coupling end and the groove width at the center portion are smaller than the maximum value of the groove width.
