Abstract
Official abstract text for this publication.
A steering device includes: a pinion shaft that has a pinion on an outer circumferential surface thereof; a rack shaft that has a rack that engages with the pinion; a rack housing that has a recess on an inner circumferential surface thereof and accommodates the rack shaft; a rack guide that has a protrusion smaller than a width of the recess in axial directions of the rack shaft, and is disposed inside the recess, the rack guide contacting an outer circumferential surface of the rack shaft and an inner circumferential surface of the rack housing, and guiding the rack shaft along an axis of the rack shaft; and a spacer that contacts one side and the other side of the protrusion in the axial directions of the rack shaft, and is disposed between an inner surface of the recess and an outer surface of the protrusion.
First claim
Opening claim text (preview).
The invention claimed is: 1. A steering device comprising: a pinion shaft that has a pinion on an outer circumferential surface thereof; a rack shaft that has a rack that engages with the pinion; a rack housing that has a recess on an inner circumferential surface thereof and accommodates the rack shaft; a rack guide that has a protrusion formed smaller than a width of the recess in axial directions of the rack shaft, and is disposed inside the recess, the rack guide contacting an outer circumferential surface of the rack shaft and an inner circumferential surface of the rack housing, and guiding the rack shaft along an axis of the rack shaft; and a spacer that contacts one side and another side of the protrusion in the axial directions of the rack shaft, that contains a central part pressed by the protrusion outwardly in a radial direction of the rack shaft, and is disposed between an inner surface of the recess and an outer surface of the protrusion. 2. The steering device of claim 1 , wherein at least one slot is circumferentially formed on the outer circumferential surface of the rack guide, and an annular contacting member is attached to the at least one slot, the annular contacting member contacting with the inner circumferential surface of the rack housing. 3. The steering device of claim 1 , wherein the spacer contacts the outer surface of the protrusion in the radial direction of the rack shaft. 4. The steering device of claim 1 , wherein the recess is formed so that the width thereof in the axial directions of the rack shaft is smaller toward an outside in radial directions of the rack shaft. 5. The steering device of claim 4 , wherein at least one slot is circumferentially formed on the outer circumferential surface of the rack guide, and an annular contacting member is attached to the at least one slot, the annular contacting member contacting with the inner circumferential surface of the rack housing. 6. The steering device of claim 1 , wherein the spacer is an elastic member having elasticity. 7. The steering device of claim 6 , wherein at least one slot is circumferentially formed on the outer circumferential surface of the rack guide, and an annular contacting member is attached to the at least one slot, the annular contacting member contacting with the inner circumferential surface of the rack housing. 8. The steering device of claim 6 , wherein the recess is formed so that the width thereof in the axial directions of the rack shaft is smaller toward an outside in radial directions of the rack shaft. 9. The steering device of claim 8 , wherein at least one slot is circumferentially formed on the outer circumferential surface of the rack guide, and an annular contacting member is attached to the at least one slot, the annular contacting member contacting with the inner circumferential surface of the rack housing.
