Abstract
A corrugated portion is formed in one end edge portion of the metallic shaft main body (), and a triangular corrugated portion () is formed in an end edge portion of the shaft auxiliary body () on the metallic shaft main body side. The metallic shaft main body () and the shaft auxiliary body () are integrated by being linearly arranged by way of meshing that brings a side of the triangular corrugated portion () on the main body side and a side of the triangular corrugated portion () on the auxiliary body side into contact with each other. A fiber orientation angle (θ) of the fiber reinforced plastic of the shaft auxiliary body () is set so as to be in the same direction as a direction of stress generated in a hypotenuse of each triangular portion under a torque load state.
