摘要：
A rack-and-pinion type steering gear for automotive vehicles including a columnar rack guide made of resin having a small coefficient of friction. An outer diameter of the rack guide in the direction perpendicular to the direction of movement of a rack bar is greater than an inner diameter of a rack guide hole for insertion of the rack guide in such a manner that the transverse cross-section of the rack guide is elliptical. With this arrangement, vibration of the rack guide in the rack guide hole due to an external force dynamically acting on the rack bar, thereby preventing generation of noise from the rack guide hole.
