A cylindrical part of a rack retainer accommodation part and an adjust screw are caulked such that a plastic deformation region by caulking straddles both a female screw part of the cylindrical part and a male screw part of the adjust screw, and the adjust screw is loosened to a point where a set load that is a force by which the rack retainer urges a rack bar falls within a predetermined range. After the set load adjusting step, the caulking step is not performed again, and fluctuations in the set load associated with the impact of caulking work after the set load adjusting step can be suppressed. Thus, it is possible to suppress fluctuations in the urging force of the rack retainer applied to the rack bar caused by caulking work which stops the rotation between the rack retainer accommodation part and the adjust screw.

APPARATUS FOR PRESSING A TOOTHED RACK AGAINST A PINION
20230115582 · 2023-04-13 ·

The disclosure relates to an apparatus for pressing a toothed rack against a pinion, having a pressure piece. The pressure piece can be arranged so as to be displaceable inside a housing and in an axial direction of a centre longitudinal axis. A bearing element that can be fixed on the housing in an axial direction with respect to the centre longitudinal axis, having a prestressing element that acts in an axial direction. Action of the prestressing element arranged between the bearing element and the pressure piece subjected the pressure piece to a prestressing force in an axial direction with respect to the centre longitudinal axis and directed away from the bearing element. A sliding element is arranged on a side, facing away from the prestressing element, of the pressure piece for the purpose of bearing against the toothed rack. In order to reduce the production outlay and/or allow a more compact design, on the side bearing against the sliding element, the pressure piece has a contour for compensating tolerances. The contour interacts with the sliding element.
