...Pinion tooth surface. Amendment 5 & 10/24 The scope of claims for utility model registration is amended as follows. To O Utility Model Registration Claims A pinion rotated by a steering handle;
It is equipped with a rack that meshes with this pinion and is driven in the axial direction as the pinion rotates, and the rack teeth at the center of the rack have a pressure angle larger than the rack teeth at both sides of the rack. In the barrier pull gear ratio type steering gear device, the pinion is processed by being shifted to the negative side so that each tooth surface of the pinion retreats by ΔT in the normal direction, and the distance between the rack and the pinion is at least A barrier pull gear ratio type steering gear device characterized in that the steering gears are made closer by Δ'l'cosecα (α is the pressure angle at the center of the rack).
