PROBLEM TO BE SOLVED: To provide a hardly loosening rack shaft.SOLUTION: A second rack tooth 12 of a VGR for meshing with a second pinion tooth 132 is formed on the tooth surface side, and a rack guide 51 for pressing to a second pinion shaft 131, slidingly contacts with the tooth reverse side, and the tooth reverse side becomes thick toward the outside in the axial direction with a steering angle 0° as the center so that pressing force to the second pinion shaft 131 becomes large toward the outside in the axial direction with the steering angle 0° as the center.SELECTED DRAWING: Figure 3
【課題】ガタつき難いラック軸を提供する。【解決手段】歯面側に第2ピニオン歯132に噛合するVGRの第2ラック歯12が形成され、歯裏側に第2ピニオン軸131に押し付けるためのラックガイド51が摺接し、舵角0°を中心として軸方向外側に向かうにつれて第2ピニオン軸131への押し付け力が大きくなるように、歯裏側は舵角0°を中心とし軸方向外側に向かうにつれて厚くなる。【選択図】図3
