PROBLEM TO BE SOLVED: To provide new coupling of a wheel bearing and a constant velocity rotary joint satisfying a request for a light structure, being easily manufactured in a manufacturing technique and avoiding a compulsory force in the rotary joint. SOLUTION: This wheel bearing is provided with the integrated constant velocity rotary joint 10 having a plate outer race 11. Driving torque is transmitted from the outer race of the constant velocity rotary joint 10 to an inner race flange 4 via a gear cutting part 5. The gear cutting part 5 is formed within the inner race flange 4 so as to support a waveform outside contour of the outer race 11 of the constant velocity rotary joint 10 in a prescribed partial range 6.
