Abstract
An inner joint component and a shaft of a constant velocity universal joint are connected in a configuration it difficult for backlash to occur. An axis hole inner diameter of an inner member of the constant velocity universal joint is unhardened, and a spline serving as a recess and projection section running along a circumferential direction is formed on an axial end outer diameter of the shaft. A hardened layer n is formed on the axial end outer diameter of the shaft. The shaft and the inner member are joined by an axial end of the shaft being pressed into the axis hole inner diameter of the inner member to incuse a shape of said recess and projection section onto the axis hole inner diameter of the inner member 20.
