摘要： A disc spring (11) is provided between a ball screw nut (3) and a hollow shaft (4), and another disc spring (12) is provided between rolling bearings (7) and a housing (6). When leftward motion of a screw shaft (2) is stopped and a rotational inertia force is applied to the ball screw nut (3), these disc springs (11) and (12) allow the ball screw nut (3) to rotate to a certain degree.

摘要： The outer diameter of a spline nut (5) and the inner diameter of a nut body holding portion (13) of a housing (6) gradually decrease in the downward direction. A ball screw protection unit (10) includes a nut body taper face (12) that is formed in the outer peripheral face of the spline nut (5), a holding portion taper face (13a) that is formed in the nut body holding portion (13), and a disc spring (11) that is provided at the upper end of the spline nut (5) and that biases the spline nut (5) in such a direction that a friction force between the nut body taper face (12) and the holding portion taper face (13a) increases, this is, the downward direction.
