Zusammenfassung:	A tail stock moving mechanism is provided, in which a tail stock that holds a workpiece with a predetermined pressure force is moved by means of a ball screw and in which the control required for holding the workpiece with the predetermined pressure force is implemented. In a step at which the tail stock (1) that holds a position of the workpiece (5) and that is supported by a ball screw (2), torque generated by a drive motor (3) that drives the ball screw (2) is detected, and in a step at which the torque reaches a predetermined reference value, and then operation of a brake (4) to limit rotation of the ball screw (2) and cutting off of an input from a power supply to the drive motor (3) are performed.
