The present invention relates to an instrument for inserting a ball for a ball screw capable of filling a ball in a short period in a ball introductory passage which an extension groove and a nut groove form and moving a ball nut from an extension shaft to a screw shaft very simply by forming a receiving groove in a lower end of the extension shaft and the extension groove which is the same as a screw groove on the outer circumferential face of the extension shaft and a method for assembling the ball screw using the same. According to the instrument for inserting a ball for a ball screw of the present invention, the receiving groove is formed in the lower end of the extension shaft for inserting a stepped protrusion formed in the upper end of the screw shaft. The extension shaft has the same radius as the screw shaft. The ball nut can move from the extension shaft to the screw shaft since the extension groove, which is the same as the screw groove formed on the outer circumferential face of the screw shaft, is formed on the outer circumferential face of the extension shaft. |
