Abstract
A vehicle steering system includes a steered shaft, and stoppers which restrict an amount of movement of the steered shaft in an axial direction. The steered shaft has first outer peripheral faces, second outer peripheral faces, and annular stepped portions. Each stepped portion includes a contact portion that faces a corresponding one of the stoppers in the axial direction, a first corner portion that has a concave curved sectional shape and connects the first outer peripheral face to an inner end of the contact portion, and a second corner portion that has a concave curved sectional shape with a larger curvature radius than that of the first corner portion, and connects the first outer peripheral face to the second outer peripheral face, at a position in front of or behind a central axis of the steered shaft.
