Abstract
This invention pertains to a rack and pinion type steering gear for an automobile and a method for cutting rack teeth in the gear. The gear comprises a housing, a pinion rotatably supported within the housing and operatively connected to a steering wheel and a rack bar supported within the housing for slidable movement in the axial direction and rotation and provided with rack teeth in engagement with the pinion. The rack teeth are formed on the rack and along a varying pitch line so that the axial movement amount of the rack varies as the pinion rotates.
