An automobile steering device is provided with a housing, a rack shaft accommodated in the housing so as to be slidable in an axial direction of the rack shaft, rack teeth formed on the rack shaft, and a long groove formed on a side of the rack shaft opposite to the rack teeth in a radial direction, and a pinion shaft inserted into the housing so as to be rotatable about the axis of the pinion shaft, on which gear teeth meshing with the rack teeth of the rack shaft are formed, and a rack support member located on a side corresponding to the long groove in the housing, on one end of which a protrusion is formed, a protrusion protrudes from an end face of the rack support and is in linear or point contact with a long groove of the rack shaft to press the rack shaft toward the pinion shaft.
本发明提供一种汽车转向器,具有壳体、齿条轴、小齿轮轴以及齿条支撑件,齿条轴以能够沿着齿条轴的轴向滑动的方式容纳在壳体中,在齿条轴上形成有齿条齿以及长凹槽,长凹槽形成在齿条轴的在径向上与齿条齿相反的一侧,且沿着齿条轴的轴向延伸,小齿轮轴以能够绕小齿轮轴的轴线旋转的方式插入在壳体中,在小齿轮轴上形成有与齿条轴的齿条齿啮合的齿轮齿,齿条支撑件在壳体中位于与长凹槽对应的一侧,在齿条支撑件的一端形成有突起,突起从齿条支撑件的端面突出并与齿条轴的长凹槽线接触或者点接触,以将齿条轴按压向小齿轮轴。
