To provide a wheel bearing device capable of preventing misconception of displayed information on internal clearance, and suppressing variation of preload after being mounted to a vehicle.SOLUTION: A wheel bearing device 1 comprises: an outer ring 2 having double-row outer raceway surfaces 2c, 2d on an inner periphery; an inward member having double-row inner raceway surfaces 3c, 4a on an outer periphery; and double-row inner-side ball row 5 and outer-side ball row 6 that are rollably housed between both raceway surfaces of the outer ring 2 and the inward member. A QR code 50 having information on the internal clearance of the wheel bearing device 1 is displayed on an external surface of the wheel bearing device 1.SELECTED DRAWING: Figure 3
