摘要: A disc spring is provided between a ball screw nut and a hollow shaft, and another disc spring is provided between rolling bearings and a housing. When leftward motion of a screw shaft is stopped and a rotational inertia force is applied to the ball screw nut, these disc springs allow the ball screw nut to rotate to a certain degree.

摘要: The outer diameter of a spline nut and the inner diameter of a nut body holding portion of a housing gradually decrease in the downward direction. A ball screw protection unit includes a nut body taper face that is formed in the outer peripheral face of the spline nut, a holding portion taper face that is formed in the nut body holding portion, and a disc spring that is provided at the upper end of the spline nut and that biases the spline nut in such a direction that a friction force between the nut body taper face and the holding portion taper face increases (downward direction).
