The present invention is to improve the structure of a wheel bearing and a sealing device. The wheel bearing includes a hub, an inner wheel, an outer wheel and an electric body. The sealing structure includes a flange. The flange includes a sealing groove. The sealant groove is formed on a part of the flange, in which the outermost side of an outer support body in a radial direction is in surface contact with one surface of the flange. A sealant is charged into the sealant groove and the part. Foreign substances, which penetrate the space between one surface of the outer support body and the other surface of the flange from the outside, are blocked, thereby preventing corrosion of the sealing device and maintaining performance thereof. Moreover, a damp lip is positioned inside the outer support body in an axial direction, thereby primarily preventing the entry of foreign substances.

    본 발명은 휠 베어링 및 실링 장치의 구조를 개선하고자 창출된 것이다. 휠베어링은 허브, 내륜, 외륜, 전동체를 포함한다. 실링 구조는 플랜지를 포함하고, 플랜지는 실런트홈을 구비한다. 상기 실런트홈은 외측 지지체의 경방향 최외측에서 플랜지 면과 접촉하는 부분에 형성하고, 상기 실런트홈 내부와 상기 접촉되는 부분에는 실런트를 충진한다. 상기 충진된 실런트에 의하여, 외부로부터 외측 지지체의 일면과 플랜지의 타면 사이로 침입되는 이물질을 차단하여, 실링 장치의 부식을 막고 성능을 지속적으로 유지할 수 있는 것이다. 또한, 댐립을 외측지지체 축방향 내측에 위치하게 하여, 외부의 이물질을 1차적으로 차단하할 수 있다.
