摘要： A housing has a screw shaft passing wall in which a through hole, through which a screw shaft passes, is formed. A spline outer cylinder is held at one end by the screw shaft passing wall, and a disc spring that biases the spline outer cylinder toward the screw shaft passing wall is arranged at the other end of the spline outer cylinder. A tapered recess is formed in one end face of the spline outer cylinder, and a tapered projection that is fitted in the tapered recess is formed in a face of the screw shaft passing wall of the housing, which faces the spline outer cylinder.

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.
