A pair of positioning locking members (27) for preventing rotation of the turret (11) engaged with each other between the base (10) and the turret (11) are detachably provided, and a screw feed mechanism composed of a ball screw (21) and a nut (25) allows the ball screw (21) or nut (see Fig. 2) (see Fig. 2) (see Fig. 2) The rotation of 25 is changed to the linear movement of the turret 11 to engage and disengage the positioning locking member 27. Here, the screw feed mechanism is driven by the first motor 24, and the turret 11 is rotated by the second motor 32. When the second motor (32) is driven to rotate and rotate the turret (11), the first motor (24) is rotated in a predetermined rotational direction with respect to the rotation of the second motor (32) in a predetermined rotational speed ratio, thereby rotating the ball screw (21) and nut (25) of the screw feed mechanism. The relative rotation of the positioning locking member (27) is prevented by the relative rotation between the two.
