Abstract

PURPOSE: To prevent a steering wheel from staggering by a method wherein the axis of the taped hole of a ball nut and the central plane of the central tooth groove of a rack are made to fall at right angles and the tooth side surfaces of the central tooth groove are ground in parallel to the central plane of the tooth groove.
CONSTITUTION: The central tooth 1a' of a sector gear 1a interlocks in the central tooth groove 2b' of a rack 2a. The central tooth groove 2b' of the rack 2a is formed smooth by grinding its tooth side surfaces. Further, the ball screw grooves 13 of a ball nut 2 is ground by a grinding shaft which moves at right angles to the central plane of the central tooth groove 2b' of the rack 2a. The force produced in the interlock between the central tooth 1a' of the sector gear 1a and the central tooth groove 2b' of the ball nut 2 can always be operated to the ball nut 2, that is, to the central axis of a ball screw shaft 11. In such a manner, since the rack 2a always interlocks in the central tooth of the sector gear by grinding operation of the ball nut 2 the steering wheel can be prevented from staggering.
