PROBLEM TO BE SOLVED: To provide a rack shaft support device capable of suppressing an occurrence of rattle noise, and reducing the friction between a pinion shaft and a rack shaft regardless of which position in an axial direction of the rack shaft a pinion tooth engages with.SOLUTION: A rack shaft support device 1 includes a rack shaft 4 having rack teeth 40 aligned in an axial direction X, and a rack guide 25 for pressing the rack shaft 4 against pinion teeth 60 that can engage with the rack teeth 40. The rack shaft support device 1 includes adjusting means 30 for adjusting pressing force F of the rack guide 25 with respect to the rack shaft 4 according to which position in an axial direction X of the rack shaft 4 the pinion tooth 60 engages with.SELECTED DRAWING: Figure 3
【課題】ラック軸の軸方向のどの位置にピニオン歯が噛合しているかに関わらず、歯打ち音の発生を抑制し、かつピニオン軸とラック軸との間の摩擦を低減することができるラック軸支持装置を提供する。【解決手段】ラック軸支持装置1は、軸方向Xに並ぶラック歯40を有するラック軸4と、ラック歯40に噛合可能なピニオン歯60に対してラック軸4を押し付けるラックガイド25とを備える。ラック軸支持装置1は、ラック軸4の軸方向Xのどの位置にピニオン歯60が噛合しているかに応じて、ラック軸4に対するラックガイド25の押付力Fを調整する調整手段30を含む。【選択図】図3
