Claims (1)

[Claims for Utility Model Registration] 1. A guide rail having a guide groove having a concave cross section in the rail width direction, and a guide rail rotatably supported at both ends of the guide rail in the rail width direction. a pulley disposed in the axial direction; a belt disposed within the guide groove of the guide rail and wound around the pulley such that its upper surface side covers the upper opening of the guide groove; A sliding body disposed in the guide groove, and a ball rolling path provided between the sliding body and the guide rail so as to be freely rollable, so that the sliding body can freely slide in the longitudinal direction of the rail. A linear guide unit comprising a plurality of supporting balls, and the sliding body moves in an axial direction in response to rotation of the pulley. 2. The linear guide unit according to claim 1, wherein the belt has a belt width that is substantially the same as a distance between inner surfaces of the guide groove. 3. The linear system according to claim 1 or 2, wherein the guide rail is provided with an opening window that allows movement of the sliding body, and a cover in which an inner edge of the opening window is close to the surface of the belt. guide unit. 4. A guide rail having a guide groove with a concave cross section in the rail width direction, and a pulley that is rotatably supported at both ends of the guide rail in the rail length direction and arranged in the axial direction of the guide rail in the rail width direction. a belt disposed within the guide groove of the guide rail and wound around the pulley so that its upper surface side covers the upper opening of the guide groove; and a belt fixed to the belt and disposed within the guide groove. A sliding body, and a large number of balls that are rollably disposed in a ball rolling path provided between the sliding body and the guide rail, and that support the sliding body so as to be slidable in the longitudinal direction of the rail. comprising a plurality of linear guide units in which the sliding body moves in the axial direction according to the rotation of the pulley;
A linear guide device characterized in that a drive shaft is provided with a single rotational drive source drivably connected to one of the pulleys of each of the linear guide units.
