PROBLEM TO BE SOLVED: To stably suppress a fall of a rack guide by a simple structure, in a rack shaft support device.SOLUTION: A rack shaft support device 15 includes a rack guide 18 accommodated in an accommodation hole 16, a plug 19 attached to an opening of the accommodation hole 16, and a compression coil spring 20 interposed between the rack guide 18 and the plug 19. The plug 19 includes a first spring bearing surface 51 which receives a first end 21 of the compression coil spring 20. The rack guide 18 includes a second spring bearing surface 52 which receives a second end 22 of the compression coil spring 20. A fall suppression mechanism 40 includes tip-narrowed tapered guide protrusions 61, 62 which are formed at least at either of the first spring bearing surface 51 and the second spring bearing surface 52, and guide inside-diameter parts 21a, 22a of the corresponding ends 21, 22 of the compression coil spring 20.SELECTED DRAWING: Figure 3
【課題】ラック軸支持装置において簡単な構造でラックガイドの倒れ抑制を安定して行う。【解決手段】ラック軸支持装置15が、収容孔16に収容されたラックガイド18と、収容孔16の開口に装着されたプラグ19と、ラックガイド18とプラグ19との間に介在する圧縮コイルばね20とを含む。プラグ19が圧縮コイルばね20の第1端部21を受ける第1ばね座面51を含む。ラックガイド18が圧縮コイルばね20の第2端部22を受ける第2ばね座面52を含む。倒れ抑制機構40が、第1ばね座面51及び第2座面52の少なくとも一方に設けられて圧縮コイルばね20の対応する端部21,22の内径部21a,22aを案内する先細りテーパ状の案内凸部61,62を含む。【選択図】図3
