Abstract:
1. A rack guide unit comprising: a rack guide accommodated in an accommodation portion formed in a housing through which a rack shaft meshed with a pinion shaft is passed, so as to be allowed to approach and move away from the rack shaft, the rack guide supporting the rack shaft such that the rack shaft is slidable in an axial direction of the rack shaft; a closure member secured to an external opening end of the accommodation portion, the external opening end being located on an opposite side of the accommodation portion from the rack shaft; at least one coned disc spring that is interposed between the closure member and the rack guide, and that urges the rack guide toward the rack shaft; a recessed portion formed in an opposed portion of the rack guide, the opposed portion being opposed to the closure member; a protrusion that is formed on the closure member, passed though the coned disc spring, and inserted in the recessed portion; and a retaining protrusion formed integrally with an outer periphery of the protrusion or formed separately from the protrusion and attached to the outer periphery of the protrusion, and located at a position closer to a distal end of the protrusion than the coned disc spring is, the retaining protrusion restraining the coned disc spring from coming off the protrusion.
