Abstract

PURPOSE:To let off frictional resistance by retaining a ball of a ball screw by seam balls to use idle rotation of the seam ball caused by rotation of front and rear balls. CONSTITUTION:A seam ball 7 is clamped between balls 3, 3. When a screw 2 is put on, the seam ball 7 is adapted to cause an idle rotation between the balls 3, 3, not opposing the rolling direction. Each contact friction lets off its resistance by rolling of the seam ball 7. The diameter of the seam ball 7 is smaller than that of the ball 3, which causes idling of the seam ball.
