According to an embodiment of the present invention, provided is a wheel bearing for rotationally mounting a vehicle wheel to a vehicle body to support the vehicle wheel. The wheel bearing according to an embodiment of the present invention can include: a rotating element that is mounted with a vehicle wheel and rotates together with the wheel; a non-rotating element that is mounted on the chassis part of a vehicle and is fixed to the vehicle body; one or more rolling elements interposed between the rotating element and the non-rotating element to support the rotating element rotationally with respect to the non-rotating element; and a center locking member used to couple the vehicle wheel to the rotating element. According to an embodiment of the present invention, the rotating element includes: a wheel mounting flange on which the vehicle wheel is mounted and a wheel pilot extended in an axial direction from a wheel side end. The center locking member is coupled to the wheel pilot, and at least one of the center locking member and the wheel pilot can be provided with a loosening prevention structure for preventing the center locking member from loosening.
