A constant velocity universal joint includes an outer joint member having an inner surface with a plurality of track grooves, an inner joint member having an outer surface with a plurality of track grooves which are paired with the track grooves of the outer joint member, and an inner surface having a shaft hole with a spline, a plurality of balls interposed between the track grooves of the outer joint member and the track grooves of the inner joint member so as to transmit torque, and a cage interposed between the inner surface of the outer joint member and the outer surface of the inner joint member so as to retain the balls, in which the inner joint member includes an axial step portion between an inlet-side end surface thereof and a spline end portion of the shaft hole so as to form a recessed end surface.
