A steering device is provided with: an outer shaft (21) disposed around a center axis (AX) and having an inner space (25) including a spline hole section (40); and an inner shaft (52) having at least a part thereof disposed within the inner space (25) and having a spline shaft section (43) having a surface disposed around the center axis (AX). The spline shaft section (43) includes: a first spline shaft section (44) having a synthetic resin first surface; and a second spline shaft section (45) having a metallic second surface, the second spline shaft section (45) being disposed adjacent to one end of the first spline shaft section (44) in an axial direction parallel to the center axis (AX), the second spline shaft section (45) including one end of an inner shaft (22), said end being disposed within the inner space (25). The distance between the center axis (AX) and the second surface is less than the distance between the center axis (AX) and the first surface. The spline hole section (40) and the first spline shaft section (44) are fitted together through the splines, and the outer shaft (21) and the inner shaft (22) are relatively axially movable. |
