Abstract
An object is to provide a motion guide apparatus that can facilitate an assembly operation. An end member (4a, 4b) including an inner peripheral side of a direction changing path (2c) is placed on an end surface in a movement direction of a moving member body (3). At least one of a pair of the end members (4a and 4b) includes an opening (21) linking to the inner peripheral side of the direction changing path (2c) to load rolling elements (42) into a circulation path. Opposing surfaces (18) of the pair of the end members (4a and 4b) to the moving member body (3) are formed in flat surfaces. The pair of the end members (4a and 4b) molded integrally with a holding portion (5) is incorporated into the moving member body (3) in a direction orthogonal to the movement direction of the moving member body (3). A lid member (7a, 7b) closes the opening (21) in the end member (4a, 4b).
