    Abstract: Disclosed is a rack bush and a rack pinion type steering apparatus having the rack bush for a vehicle, which can smoothly support a load in an axial direction and a vertical direction of a rack bar so that it is possible to reduce abnormal abrasion of the rack bush, reduce a rattle noise caused by external force transferred through the rack bar during movement of the rack bar, and prevent damage to the rack bar and a pinion through distribution of the load due to an external impact on the shaft.

    Abstract: Disclosed is a rack bar supporting device of a rack and pinion type steering apparatus for a vehicle. The disclosed device can prevent free movement from increasing by automatically adjusting a predetermined free movement even when wear occurs in a support yoke after degradation of driving durability of the vehicle, and can prevent a noise from occurring caused by an increase of free movement when the support yoke collides with a yoke plug by an impact reversely input from an uneven road surface, etc. This can provide a comfortable steering feeling to the driver.

    Abstract translation: 公开了一种用于车辆的齿条和小齿轮转向装置的齿条支撑装置。 所公开的装置可以通过自动调节预定的自由运动来防止自由运动，即使在车辆的驾驶耐久性下降之后在支撑轭中发生磨损，并且可以防止当支撑件的自由运动增加时引起的噪音 轭通过从不平坦路面反向输入的撞击等与轭塞碰撞。这可以为驾驶员提供舒适的转向感。
