In a ball nut mechanism the ball return means for recirculating the balls from one end of the mechanism to the other is designed as a tube which is substantially U-shaped, the end portions of the tube being fitted in bores in the nut body of the mechanism. The tube furthermore is countersunk in a channel running transversally over the nut body between said bores. On a level above the tube resting in the channel, this is provided with a longitudinal groove in each of its side walls, in which grooves a locking member is insertable. Said locking member, being of a deformable material, is so much longer than the channel that it extends out over enlarged portions of the bores, where it is bent down over the tube, thereby being secured against longitudinal displacement. |
