て設けて成るボールねじ。 A screw shaft with a spiral ball groove on the outer circumferential surface,
A nut that can be externally fitted onto a screw shaft and has a spiral ball groove on its inner peripheral surface that corresponds to the ball groove of the screw shaft, and a spiral formed by both ball grooves that are formed by externally fitting the nut onto the screw shaft. The nut is provided with a plurality of balls rotatably filled into the spiral passage, and the nut is provided with a through hole extending in the axial direction to serve as a return passage for returning and circulating the balls rotating in the spiral passage. At the same time, a guide groove is recessed from the end surface and allows the ball to rotate by communicating with the ball groove on the inner circumferential surface and the through hole. The ball screw is provided with a conveying piece protruding from the joint surface of the lid member with the nut, which is positioned in the guide groove and enables the ball to be conveyed between the ball groove of the screw shaft and the guide groove.
