Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a ball screw capable of preventing noise by adding a simple mechanism to a common ball screw having a relative clearance, and reducing the relative clearance between a screw spindle and a nut. SOLUTION: The ball screw 40 includes the screw spindle 2, the nut 3 and a plurality of balls 4. The ball spindle 40 is equipped with an elastic member 41, and by moving the nut 3 in the initial restoring direction of the elastic member 41 by an elastic force of the elastic member 41, the relative clearance between the screw spindle 2 and the nut 3 is reduced.
