To provide a wheel hub for improving working efficiency in dismounting a wheel while suppressing an increase in the cost and occurrence of deviation between rotation centers of a wheel and the wheel hub.

The wheel hub 1 includes a hub body 10 and an annular member 11. The hub body 10 integrally includes a hub shaft portion 2 supported by an axle and a mating portion 4 disposed on the periphery of the rotary shaft of the hub shaft portion 2. The mating portion 4 has an outer face 4a in a male screw shape along a circumferential surface around the rotary shaft of the hub shaft portion 2. The inner circumferential surface 11a of the annular member 11 has a female screw shape which is screwed to the outer face 4a of the mating portion 4. By fastening the annular member 11 by screwing to the mating portion 4, the annular member 11 is moved inwardly in a vehicle width direction and mounted on the mating portion 4. Shaft holes 7, 8 of wheels 5, 6 are fitted from the outside in the vehicle width direction to the annular member 11 in a state that the annular member 11 is mounted on the mating portion 4.
