ABSTRACT:
A rack-pinion steering mechanism for a vehicle, comprises a housing, a pinion shaft having housed within the housing a pinion and first and second supporting portions respectively disposed to opposite sides of the pinion, and a rack shaft having a rack meshed with the pinion within the housing, the rack shaft being shiftable in an axial direction thereof by rotation of the pinion to shift a tie rod axially. The second supporting portion of the pinion shaft is supported within the housing by a corresponding bearing, and the first supporting portion is supported within the housing by a pair of angular rolling bearings having respective inner races fixed to the first supporting portion and respective outer races abutted with one another. The outer races are held with a predetermined pre-load in abutment between a stepped portion of the housing and a nut threaded to the housing and pressing against the outer races but not pressing against the inner races.
