  • Patent number: 12168491
    Abstract: 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.
