Abstract
An outer joint member () and an inner joint member () each have a shaft portion (and) having a male spline formed thereon, and shaft clamps () are press-fitted onto the respective shaft portions (and). Each of the shaft clamps () includes: a connection hole () that has a female spline formed therein, extends from a first axial end partway toward a second axial end, and has no quench-hardened layer; and a cylindrical portion () that has no female spline formed therein and extends from the second axial end partway toward the first axial end. The shaft portions (and) each have a quench-hardened layer on the outer circumference thereof. The inner diameter of the connection hole () at a portion having no female spline formed therein is less than the outer diameters of the shaft portions (and).
