摘要：
A ball screw nut, into which a ball screw shaft is screwed, is coupled with a first cylindrical member disposed in a periphery of the ball screw shaft so as not to rotate with each other. The ball screw nut and the first cylindrical member are rotatably supported on a second cylindrical member by way of balls arranged so as to form two rows. One end portion of the ball screw nut is spline-fitted with one end portion of the first cylindrical member. Two rows of ball bearing raceways are formed on an outer peripheral face of the ball screw nut.
