摘要

The rack and pinion steering gear (1) has steering gear housing (2) having pressure piece (5) which pushes toothed rack (3) against drive gear, and rotatably mounted roller bearings (10) formed on pressure piece to mount rack back (6) and held by ball socket (14). A rolling element (11) is extended in axial direction of rack. The rolling element has width smaller than diameter of ball, on peripheral surface of rack back. The ball socket has opening with diameter smaller than diameter of rolling bearing so that rolling bearings are supported and rolled on rolling element of rack back.
