The present invention relates to a seal for a wheel bearing for preventing foreign matter from entering the wheel bearing. The object of the present invention is to provide the seal for a wheel bearing, wherein a structure of a main branch having magnetic force in a lip unit of a rubber unit and a multiple branch protruding from one end of the main branch is applied. Accordingly, when one of the multiple branches in close contact with the surface of the seal outer race unit wears out to lose a sealing function, the other one of the multiple branches can perform the sealing function while automatically coming in close contact with the surface of the seal outer race unit.

    본 발명은 휠베어링의 내부로 이물질이 침투하는 것을 방지하기 위한 휠베어링용 씰에 관한 것으로서, 러버부의 립(lip) 부분에 자기력을 가지는 메인 브랜치 및 상기 메인 브랜치의 일단부에 돌출 형성되는 멀티플 브랜치의 구조를 적용하여, 상기 멀티플 브랜치 중 씰외륜부의 표면에 밀착되어 있는 하나의 브랜치가 마모되어 씰링 기능이 상실되면 상기 멀티플 브랜치 중 다른 하나의 브랜치가 자동으로 씰외륜부의 표면에 밀착되면서 씰링 기능을 수행할 수 있는 휠베어링용 씰을 제공하는데 목적이 있다.
