In the ball screw moving device for linearly moving the screw shafts in the axial direction, the screw shafts are screwed onto the screw shaft with the ball nut sandwiched therebetween while being separated from each other in the axial direction by a predetermined distance shorter than the overall length of the screw shaft. a pair of supporting ball nuts disposed so as to be movable in the axial direction, and each of the pair of supporting ball nuts is immovable relative to the axial direction and rotatable about the axial center via bearings; and a slide member that rotatably supports the screw shaft via the supporting ball nut.
