A thrust washer of a hub comprises a washer body(21), an insertion portion(23) and an insertion step(25). The washer body is formed in a circular cap shape having a through hole(19) in the center. One end of the washer body is formed with the insertion portion protruded in the circumferential direction. The insertion step with a sharp end is formed to be inserted along the outer circumferential surface of rear end of the hub in the inner circumferential surface of the insertion portion.
