PROBLEM TO BE SOLVED: To provide a deflector for a ball screw, which hardly causes damage in a tongue part thereof to solve such problems that the strength of a tongue part can not withstand when a collision load of a ball is large, the tongue part causes a fatigue failure therein due to repetition of use, and the like, in a deflector used for a ball screw, and to provide a deflector-type ball screw that includes the deflector.SOLUTION: In the deflector for a ball screw, the tongue part 10 is formed into a gothic arc shape or the like so as to bring the tongue part into contact with the ball 7 at two points instead of one point, thereby distributing a collision load and wear to the points. |
