ABSTRACT:
A ball screw device includes a ball returning tube which is formed by covering the outer periphery of the tube with a heat shrinkable resin tube and heating the thus formed tube, formed of two halves, to shrink the heat shrinkable resin tube so that the two halves of the ball returning tube can be made integral. The ball screw device is advantageous in that it generates little noise, the ball returning tube has sufficient strength despite the splittable structure and manufacturing of the device is easy.
