To suppress that a steering shaft in a vehicle steering device is rotated following rotation of a screw mechanism.SOLUTION: A steering shaft support structure 80, which is provided on a steering device 100 which converts rotational movement of a motor 30 into axial movement of a steering shaft 6 via a screw mechanism (ball screw mechanism 40), comprises the steering shaft 6, a housing 5 which accommodates the steering shaft 6, and a shaft guide 81 which is fixed in the housing 5 and contacts the steering shaft 6. The steering shaft 6 has a first part (non-arc-shaped part 612) in which a distance from a center P to an outer edge of the steering shaft 6 in a cross-sectional view in a plane orthogonal to an axial direction of the steering shaft 6 is not constant, the shaft guide 81 has a second part (contact part) having a shape along the first part, and the second part contacts the first part.SELECTED DRAWING: Figure 3

    【課題】車両の転舵装置における転舵軸がネジ機構の回転に追従して回転してしまうことを抑制する。【解決手段】転舵軸支持構造80は、モータ30の回転運動を、ネジ機構(ボールネジ機構40)を介して転舵軸6の軸方向の移動に変換する転舵装置100に備わる転舵軸支持構造80であって、転舵軸6と、転舵軸6を収容するハウジング5と、ハウジング5内で固定されて、転舵軸6に当接する軸ガイド81とを備え、転舵軸6は、当該転舵軸6の軸方向に直交する面での断面視において、転舵軸6の中心Pから外縁までの距離が一定でない第一部分(非円弧状部612)を有し、軸ガイド81は、第一部分に沿う形状を有する第二部分(当接部)を有しており、第二部分が第一部分に当接している。【選択図】図3
