The invention provides a shape of a wall surface of a direction changing path of a roller bearing for an endless linear motion. The outer wall surfaces of the direction changing path are formed convex outward. This convex outward outer wall surface can be formed as a spherical band with its center of curvature lying on the axis of revolution of the direction changing path. Such outer wall shape allows a minimum play of the rollers of the roller bearing for an endless linear motion during the direction changing motion through the direction changing path. As a result, stick-slip motion as well as the resistance of the rollers during the direction changing motion are reduced. Accordingly, the total the resistance of the roller bearing for an endless linear motion is reduced, producing an improved roller bearing for an endless linear motion as a whole.
