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