Abstract

A propeller shaft includes a first shaft and a second shaft. The first shaft has a torque transmission face in which a plurality of fine grooves extending in a first direction (face width direction) is formed. The second spline shaft is coupled to the first spline shaft so as to be movable relative to the first spline shaft in the axial direction of the first spline shaft, and has a torque transmission face in which a plurality of second fine grooves extending in a second direction that crosses the first direction is formed.
