PURPOSE: A propeller shaft for vehicle is provided to reduce manufacturing time and weight of tube by solving damage conduct problem without adding a separate structure by a cutting edge protrusion on a press part of a yoke. CONSTITUTION: A propeller shaft for vehicle comprises a tube, a yoke(12) and a cutting edge protrusion(14). The tube is carbon fiber strengthening composite. The yoke is pressed in both end part of the tube. The cutting edge protrusion is formed in the press part of the yoke. If the load is delivered through the yoke in axial direction in the vehicles head-on collision, a notch, formed by the cutting edge protrusion, induces the axial direction damage of the tube. The cutting edge protrusion is formed on the boundary surface of a press part(13) of the yoke in axial direction. |
