PROBLEM TO BE SOLVED: To provide a rack guide mechanism which inhibits inclination of a moving member in a more secure manner and thereby improves steering feeling, and to provide a vehicle steering device including the rack guide mechanism.SOLUTION: A rack guide mechanism includes: a rack housing; a moving member which is housed in a cylinder part 44 of the rack housing so as to move forward and rearward and comprises a support yoke 51 and a sheet member 52; a coil spring 53 which biases the moving member toward a back surface 3a of the rack shaft 3 and serves as an elastic member; and first screw members 551, 552 which are threadedly engaged with first and second screw holes 441, 442 penetrating through the interior of the cylinder part 44. Tip parts 551a, 552a of the first and second screw members 551, 552 are butted with an outer peripheral surface 51c of the support yoke 51 to restrict inclination of the support yoke 51 relative to the cylinder part 44.SELECTED DRAWING: Figure 5
【課題】移動部材の傾きをより確実に抑制し、以って操舵感を向上させることができるラックガイド機構及びそのラックガイド機構を備えた車両用操舵装置を提供する。【解決手段】ラックガイド機構は、ラックハウジングと、ラックハウジングの筒部44内に進退移動可能に収容されたサポートヨーク51及びシート部材52からなる移動部材と、移動部材をラックシャフト3の背面3aに向かって付勢する弾性部材としてのコイルばね53と、筒部44の内外を貫通した第1及び第2螺合孔441,442に螺合する第1及び第2ねじ部材551,552と、を有し、第1及び第2ねじ部材551,552の先端部551a,552aがサポートヨーク51の外周面51cに突き当たることにより、筒部44に対するサポートヨーク51の傾きが規制される。【選択図】図5
