A rack-and-pinion steering gear device has a mechanism for adjusting backlash and eliminating lost motion or play between a rack and a pinion. The pinion is formed on a pinion shaft angularly movably supported by a pinion holder, the pinion shaft having an axis out of alignment with the central axis of the pinion holder. The pinion holder is angularly movably supported in a housing such that the relative positions of these components with respect to each other are adjustable. A subpinion is supported on the pinion shaft for angular movement with respect to the pinion, the pinion and the subpinion being held in mesh with the rack. The subpinion is normally urged by a resilient member in a direction to turn with respect to the pinion. By adjustably turning the pinion holder with respect to the housing, the backlash between the rack and the pinion is adjusted and the lost motion or play between the rack and the pinion is eliminated by the subpinion. |
