Abstract: In a multi-piece deflector for a ball screw mechanism, the positioning precision of a tongue with respect to a ball rolling passage can be improved, balls can be recirculated in a proper manner at all times, and damages to the tongue can be avoided. A deflector main body (40) which is fitted to the nut (7) is provided with a tongue (50) and a main body side ball guide groove (51) defining a part of a circular cross section, and a component piece (60) which is fitted to the deflector main body (40) is provided with a component piece side ball guide groove (68) defining a remaining part of the circular cross section.

Abstract: In a plastic nut for a ball screw formed by injection molding fiber reinforced plastic, the reduction in precision over time due to wear is minimized. A thread groove is ground until the fibers in matrix plastic are exposed on the surface of the thread groove.

Abstract: In a ball screw (1), the positioning of the deflectors to the nut is facilitated, and the deflectors are prevented from being dislodged in the radially outward direction from the nut. The ball screw (1) includes a screw shaft (3), a nut (7), a pair of deflectors (13) inserted in respective receiving holes (14) of the nut and a plurality of balls (8). The nut (7) is provided with a guide portion (42) configured to cooperate with a corresponding guide portion (41) provided on the deflector (13) so that the insertion of the deflector (13) into the respective receiving holes (14) is guided in a direction at an angle to the radial direction of the nut.
