ールねじ。 A screw shaft and a cylindrical nut attached to the screw shaft are fitted in the axial direction to transmit rotational force to the nut or linearly from the nut by rotation of the screw shaft. A nut member consisting of an actuating body that receives a moving force, and a plurality of balls that are housed in thread grooves formed inside when the nut part is attached to a screw shaft, and one side of the nut part. A ball screw in which a portion is cut out in a direction parallel to the axis to form a flat portion, and a return tube for returning the ball from one end of the nut portion to the other end is attached to the flat portion,
A flat part substantially similar to the above flat part is formed on one side of the nut part located on the opposite side of the above one side part, and at least one of this flat part or a part of the actuating body corresponding to this flat part is formed. A ball screw characterized by being equipped with a balance holder to prevent rotational runout.
