In an electric power steering system, there is provided a ball screw deflector configured to make it possible to easily measure the whole length of each of deflector pieces (42, 43). A mating face (S3) of each of the deflector pieces (42, 43) and end faces (S1, S2) of the deflector pieces (42, 43) are parallel to each other, and have an angle corresponding to a lead angle (A1) of a ball screw portion. Thus, it is possible to reduce the amount of material required to form each of the deflector piece pieces (42, 43). In addition, it is possible to easily measure the overall length of each of the deflector pieces (42, 43) with the use of measuring equipment such as a vernier caliper.
