Abstract

A rack and pinion gear system in a gear casing for vehicle steering has a spring biased rack against the pinion at one side of the pinion to maintain pinion engagement with the rack. On the other side of the pinion is a generally semicircular bracing bushing encompasssing the pinion and slightly spaced therefrom to brace the pinion in event of bending due to operational stresses. The bracing bushing is carried for support against the gear casing and secured in any suitable manner or may be cast as part of it.
