Abstract
PURPOSE:To improve quality and reduce cost by installing an annular flange for fixing a transmission member which extends outwardly in the radial direction at the near center of the outer periphery of a nut and providing a difference in the screw pitch of the nut. CONSTITUTION:An annular flange 7 extending outwardly in the radial direction is installed in the vicinity of the center of the outer periphery of a nut 4. Therefore, even if the carburization hardening is applied onto the screw groove 6 on the inner periphery of the nut 4, the degree of the thermal treatment strain generated on the inner periphery of the both edge parts of the nut is reduced. and the depth of the hardened layer in the grinding of the screw groove 6 can be finished uniformly, and the basic metal of the nut 4 is prevented from being exposed outside. Further, since a ball 5 which rolls between the screw grooves 6 and 3 of the nut 4 and the screw shaft 2 is provided with a pitch difference on the screw groove, a prepressure is applied by the pitch difference, and the backlash in the relative shift between the screw shaft 2 and the nut 4 is eliminated. Therefore, the responsiveness for the drive supplied from a transmission member 13 is improved.
