Abstract
According to an aspect, a steering device includes: an outer shaft disposed around a center axis and includes an inner space with a spline hole portion; and an inner shaft that includes a spline shaft portion including a surface disposed around the center axis, at least a part of the inner shaft being disposed in the inner space. The spline shaft portion includes a first spline shaft portion including a first surface formed of synthetic resin and includes a second spline shaft portion including a second surface formed of metal. A distance between the center axis and the second surface is smaller than a distance between the center axis and the first surface. The spline hole portion and the first spline shaft portion are spline-fitted to each other, and the outer shaft and the inner shaft are relatively movable in the axial direction.
