Zusammenfassung:PROBLEM TO BE SOLVED: To provide a ball screw which can lubricate in the saved space across a long term. SOLUTION: In this ball screw, lubrication members 27, 28 are arranged on the parts 4C, 4D adjacent to the closed loop track 20 constituted by a ball guide 7 out of the inside spiral groove 4 of a nut member 3. Therefore, when the screw member 1 is relatively rotated for the nut member 3, the outside spiral groove 2 of the screw member 1 is lubricated by moving to the lubrication members 27, 28 while sliding. Therefore, the lubrication is carried out by utilizing the unuse parts 4C, 4D of the inside spiral groove 4 in which the ball 6 for supporting does not run effectively.
