<p>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).</p> |
