Abstract

PURPOSE: To reduce the number of employed balls and eliminate a ball circulating mechanism by a method wherein annular grooves are formed on the internal surface of a cylindrical moving body fitted loosely to a screw threaded shaft and the balls are accommodated in the intersecting parts of this annular grooves and the screw groove of the screw threaded shaft.
CONSTITUTION: Three start screws are formed on the screw threaded shaft 2 excluding the both end parts thereof and annular stoppers 3 are fixed to the both ends of the screwed section thereof. Three annular grooves 9 are provided on the internal surface of the cylindrical moving body 4 fitted to this screw threaded shaft 2 in the longitudinal direction thereof with the same space as the screw groove 8 on the screw threaded shaft 2 and a ball holding cylinder 5 is interposed between the cylindrical moving body 4 and the screw threaded shaft 2. Circular holes 10 are formed on the peripheral wall of the ball holding cylinder 5 at the parts wherein the annular walls 9 and the screw groove 8 are intersecting while the balls 6 are fitted loosely within respective circular holes 10. The ball holding cylinder 5 is provided with pawls 5a capable of being engaged with pawls 3a on the stoppers 3 when the cylindrical moving body 4 has come to the end of the moving stroke thereof.
