Abstract
The durability of a rack bushing which supports of a rack shaft of a rack and pinion steering system is improved. A bushing holder 18 is fixedly mounted in one end of a steering body 6, and a rack bushing 2 is held within the bushing holder in order to support a rack shaft 4 in a slidable manner. An end of the rack bushing is formed with a locking flange 2b, which fits in an annular groove 18a formed in the bushing holder. Adjacent to the end where the flange is formed, the inner peripheral surface of the rack bushing is formed with a portion of an increased diameter 2c which avoids its contact with the rack shaft. The portion of an increased diameter extends inward beyond the region of the annular groove and a chamfer 18c formed on sidewall of such groove of the bushing holder.
