摘要： An electrically driven power steering apparatus is structured such that a large impact on a rack shaft occurs upon an impingement of a steering stopper, and, even when an axial force acting on a ball bearing of a presser member becomes zero, a rotation of the presser member is hindered by caulking c at a thin plate member. Therefore, the presser member does not slacken, and a predetermined axial force can be given again to the ball bearing when the impact dissipates. The thus structured power steering apparatus exhibiting, though the cost is low, an excellent shockproof characteristic and capable of preventing the bearing from coming off a ball screw nut, can be provided.
摘要翻译：电动动力转向装置被构造成使得在转向挡块的撞击时对齿条轴产生大的冲击，并且即使当作用在压紧构件的滚珠轴承上的轴向力变为零时，压脚的旋转通过在薄板构件上铆接c阻碍构件。因此，压紧部件不松弛，并且当冲击消散时可以再次给予球轴承预定的轴向力。这样构成的动力转向装置虽然成本低，但能够提供优异的防震特性，能够防止轴承脱离滚珠丝杠螺母。

摘要： An electrically driven power steering apparatus is structured such that a large impact on a rack shaft (22) occurs upon an impingement of a steering stopper, and, even when an axial force acting on a ball bearing (25) of a presser member (30) becomes zero, a rotation of the presser member (30) is hindered by caulking c at a thin plate member (30b). Therefore, the presser member (30) does not slacken, and a predetermined axial force can be given again to the ball bearing (25) when the impact dissipates. The thus structured power steering apparatus exhibiting, though the cost is low, an excellent shockproof characteristic and capable of preventing the bearing from coming off a ball screw nut, can be provided.
