Abstract
In a ball screw (), comprising a screw shaft (), a nut () threaded onto the screw shaft via a plurality of balls () received in a raceway () defined between the two parts, an end deflector receiving recess () is formed on each axial end thereof to complementarily receive an end deflector () which defines a part of the raceway in cooperation with an opposing part of the nut, wherein the end deflector is provided with a pair of engagement claws () that engage corresponding parts of the thread () formed on the nut. Thereby, the need for a special engagement feature or other arrangement for attachment is eliminated, and still a highly firm and accurate engagement is ensured between the nut and the end deflector.
