Abstract

A ball screw drive which has a ball nut arranged on a spindle. The ball nut has a nut element and a deflecting element that deflects balls out of one end of an endless ball channel defined by the ball nut and the spindle to a beginning of the ball channel. The deflecting element is retained on the nut element through a clip. At least one clip leg of the clip has a first, resiliently biased section and a second section separated from the first section by a slit. The first section resiliently suspends the deflecting element on the nut element and the second section retains the clip inseparably on the deflecting element.
