发明名称 BALL SPLINE
摘要 <P>PROBLEM TO BE SOLVED: To provide a ball spline which can prevent indentation in a spline track even when receiving excessive torque. Ž<P>SOLUTION: In a screw spindle 2, an upper end section (torque input side end section) of a part located within a ball spline outer case 4 is relatively easier to twist compared with a lower end section (opposite torque input side end section) by a torque applied through a ball screw nut; and each of spline tracks 4a, 4b of a ball spline outer case 4 is inclined according to a twist of this screw spindle 2.
