断していることを特徴とするボールねじ。Engraved on the inner and outer peripheries of the nut and screw shaft. In the ball screw in which a plurality of balls are interposed between the groove surfaces of a threaded groove, the nut has a nut body in which a part of the circumference is cut out from the inner circumferential surface to the outer circumferential surface over a part of the circumference in the axial direction. , a nut adjustment part having a shape that fits the notch of the main body and supported by the nut main body so as to be slidable in the radial direction, and further including a spring that pushes the adjustment part toward the nut main body. The nut adjustment section presses the ball against the screw shaft by the force of this spring, and the nut adjustment section has a smooth inner peripheral surface, and the thread groove of the nut is interrupted at the nut adjustment section. A ball screw characterized by:
