なくラックバ−の支持か不安定である欠点があった。Conventionally, this lengthening means has been used to bring the support into frictional contact or rolling on the rack bar, and to transfer these frictional or rolling agitation contacts to the entire rack bar! Ihl1li
However, in such conventional technology, when the support body is brought into frictional contact with the rack bar, it is difficult to perform full steering even when traveling straight. When the steering wheel slips, the steering efficiency is poor (there was a drawback. When the support body rolls into contact with the rack bar, the entire steering wheel becomes Not only could it not be adjusted properly at 11 o'clock, but the support of the rack bar was also unstable.

うドしたものである。(Means for Solving the Problems) In order to solve the problems of the conventional C method as described above, in the present invention, when a rack bar is loaded with a high load, it rolls on the rack bar. The rack bar is supported by the rollers that touch it, and the rack bar is supported by the yoke π that comes into frictional contact with the rack bar when a low load II is applied.
