ABSTRACT:
A power transmission shaft such as a spline shaft and a serration shaft is provided which has improved static strength and fatigue strength. In a power transmission shaft, a diameter expansion surface is formed in a valley section of a tooth on the opposite side of a shaft end. First blunt sections in the shape of a curved surface are formed in corners between the diameter expansion surface and a tooth surface adjacent to the diameter expansion surface, in order to blunt edges.
