According to an embodiment of the present invention, provided is a wheel bearing for a vehicle, wherein a wheel of a vehicle is rotatably mounted on a vehicle body to be supported. According to an embodiment of the present invention, the wheel bearing for a vehicle comprises: a rotation element in which a wheel of a vehicle is mounted to rotate with the wheel of the vehicle; a non-rotation element mounted and fixed to a vehicle body; a plurality of rolling elements interposed between the rotation element and the non-rotation element; and a sealing member mounted between the rotation element and the non-rotation element to prevent inflow of external foreign substances or leakage of internal lubricating oil. According to an embodiment of the present invention, the sealing member may include a frame mounted on any one of rotation elements and non-rotation elements of the wheel bearing, and an elastic sealing part attached to the frame. According to an embodiment of the present disclosure, the elastic sealing portion may include one or more elastic sealing lips, and one or more of the elastic sealing lips may be formed as asymmetrical contact sealing lips in which an interference amount is unevenly formed along a circumferential direction.

    본 발명의 일 실시예에 따르면, 차량의 휠을 차체에 회전 가능하게 장착하여 지지하는 차량용 휠베어링이 제공된다. 본 발명의 일 실시예에 따른 차량용 휠베어링은 차량의 휠이 장착되어 차량의 휠과 함께 회전하는 회전요소와; 차체에 장착되어 고정되는 비회전요소와; 회전요소와 비회전요소 사이에 개재되는 복수의 전동체와; 회전요소와 비회전요소 사이에 장착되어 외부 이물질의 유입이나 내부 윤활유의 누출을 방지하는 씰링부재를 포함할 수 있다. 본 발명의 일 실시예에 따르면, 씰링부재는 휠베어링의 회전요소와 비회전요소 중 어느 하나에 장착되는 프레임과 프레임에 부착된 탄성 씰링부를 포함할 수 있다. 본 발명의 일 실시예에 따르면, 탄성 씰링부는 하나 이상의 탄성 씰링립을 포함하고, 탄성 씰링립 중 하나 이상은 원주방향을 따라 간섭량이 불균일하게 형성되는 비대칭 접촉 씰링립으로 형성될 수 있다.
