Zusammenfassung:	A wheel bearing according to one embodiment of the present invention can comprise: a first seal member disposed between first outer peripheral surfaces of first cylinder parts of an outer ring and an inner ring so as to seal the gap between the outer ring and the inner ring; and a second seal member press-fitted into a second cylinder part of the inner ring. The second seal member can include: a slinger having an axial outer end portion spaced from a first seal member and a first end surface; a first seal lip which is coupled to the axial outer end portion of the slinger, and which has a first seal part coming in contact with a portion of the first seal member and a second seal part coming in contact with a portion of the first cylinder part; and a second seal lip coupled to the slinger so as to be spaced from the first seal lip in an inwardly axial direction. L'invention concerne un roulement de roue qui, selon un mode de réalisation, peut comprendre : un premier élément d'étanchéité disposé entre des premières surfaces périphériques externes de premières parties cylindre d'une bague externe et une bague interne de façon à sceller l'espace entre la bague externe et la bague interne ; et un second élément d'étanchéité ajusté par pression dans une seconde partie cylindre de la bague interne. Le second élément d'étanchéité peut comprendre : un anneau gicleur ayant une partie d'extrémité externe axiale espacée d'un premier élément d'étanchéité et une première surface d'extrémité ; une première lèvre d'étanchéité qui est couplée à la partie d'extrémité externe axiale de l'anneau gicleur et qui a une première partie d'étanchéité venant en contact avec une partie du premier élément d'étanchéité et une seconde partie d'étanchéité venant en contact avec une partie de la première partie cylindre ; et une seconde lèvre d'étanchéité couplée à l'anneau gicleur de façon à être espacée de la première lèvre d'étanchéité dans une direction axiale vers l'intérieur. 본 개시의 일 실시예에 따른 휠 베어링은, 외륜과 내륜의 제1 원통부의 제1 외주면 사이에 배치되어 외륜과 내륜 사이를 시일하는 제1 시일 부재와, 내륜의 제2 원통부에 압입되는 제2 시일 부재를 포함할 수 있다. 제2 시일 부재는, 제1 시일 부재 및 제1 단부면으로부터 이격되는 외측 축방향 단부를 구비하는 슬링거, 슬링거의 외측 축방향 단부에 결합되고, 제1 시일 부재의 일부에 맞닿는 제1 시일부와 제 1 원통부의 일부에 맞닿는 제2 시일부를 구비하는 제1 시일 립, 및 제1 시일 립으로부터 내측 축방향으로 이격되도록 슬링거에 결합되는 제2 시일 립을 포함할 수 있다.
