摘要： Provided is a rolling guiding device which makes it possible to easily provide a movement block with an endless circulation path for the balls even in a case of a small-sized rolling guiding device using balls of a relatively small diameter and which can be produced easily and at low cost. In one surface of a movement block (2) opposed to a rolling groove (13) of a raceway rail (1), there is formed a track groove (21) through which balls (3) makes an endless circulation. The track groove (21) is composed of: a load straight-line groove (22) which allows, between the track groove (21) and the rolling groove (13) of the raceway rail (1), the balls (3) to roll while bearing a load; a pair of ball deflection grooves (24) and (24) respectively provided at both ends of the load straight-line groove (22) and adapted to release the balls (3) having rolled through the straight-line groove (22) from the load and to change their rolling direction, causing the balls (3) to leave the rolling groove (13) of the raceway rail (1); and a non-load straight-line groove (23) for transferring the ball (3) in a non-load state from one deflection groove (24) to the other ball deflection groove (24).

摘要： A rolling guiding device in which a movement block can be easily provided with an endless circulation path for balls even if the device is small-sized and the diameter of the balls is reduced and which can be produced simply and at low cost. A track groove (21), in which balls (3) circulate endlessly, is formed in that one side of a movement block (2) which is opposite a rolling groove (13) of a raceway rail (1). The track groove (21) has a load straight-line groove (22) in which the balls (3) roll while applying a load between the track groove (21) and the rolling groove (13) of the raceway rail (1), a pair of ball deflection grooves (24) that are arranged on both ends of the load straight-line groove (22) and that release the balls (3), which rolled in the straight-line groove (22) to the ball deflection grooves (24), from the load and change the direction of rolling of the balls (3) to allow them to leave from the rolling groove (13) of the raceway rail (1), and a non-load straight-line groove (23) for transferring the ball (3) in a non-load state from one deflection groove (24) to the other ball deflection groove (24).
