According to one embodiment of the present invention, provided is a vehicle wheel bearing that rotatably mounts a vehicle wheel to a vehicle body and supports the vehicle wheel. The vehicle wheel bearing, according to one embodiment of the present invention, may comprise: a rotating element that rotates along with the wheels of a vehicle; a non-rotating element that is fixedly mounted to a vehicle body; a plurality of rolling bodies interposed between the rotating element and non-rotating element; and a sealing member mounted between the rotating element and non-rotating element to prevent foreign substances from flowing thereinto. According to one embodiment of the present invention, the sealing member may comprise: a first member mounted on one of the rotating element and non-rotating element of the wheel bearing; and a second member mounted on the other of the rotating element and non-rotating element of the wheel bearing. According to one embodiment of the present invention, the first member (600) of the sealing member may comprise a first frame and an elastic sealing part attached to the first frame, and the second member of the sealing member may comprise a second frame and an elastic member attached to the second frame. According to one embodiment of the present invention, the elastic sealing part may comprise one or more sealing lips that make contact with the second member of the sealing member to form a seal, and the second member may have a convex-concave part in all or a portion of the area in which the sealing lips make contact therewith.

    Selon un mode de réalisation de la présente invention, est proposé un roulement de roue de véhicule qui fixe de manière rotative une roue de véhicule à une carrosserie de véhicule et supporte la roue de véhicule. Le roulement de roue de véhicule, selon un mode de réalisation de la présente invention, peut comprendre : un élément rotatif qui tourne conjointement avec les roues d'un véhicule ; un élément non rotatif qui est monté de manière fixe sur une carrosserie de véhicule ; une pluralité de corps de roulement interposés entre l'élément rotatif et l'élément non rotatif ; et un élément d'étanchéité monté entre l'élément rotatif et l'élément non rotatif pour empêcher des substances étrangères de s'écouler à l'intérieur de ceux-ci. Selon un mode de réalisation de la présente invention, l'élément d'étanchéité peut comprendre : un premier élément monté sur l'un de l'élément rotatif et de l'élément non rotatif du roulement de roue ; et un second élément monté sur l'autre de l'élément rotatif et de l'élément non rotatif du roulement de roue. Selon un mode de réalisation de la présente invention, le premier élément (600) de l'élément d'étanchéité peut comprendre un premier cadre et une partie d'étanchéité élastique fixée au premier cadre, et le second élément de l'élément d'étanchéité peut comprendre un second cadre et un élément élastique fixé au second cadre. Selon un mode de réalisation de la présente invention, la partie d'étanchéité élastique peut comprendre une ou plusieurs lèvres d'étanchéité qui entrent en contact avec le second élément de l'élément d'étanchéité pour former un joint d'étanchéité, et le second élément peut présenter une partie convexe-concave dans la totalité ou une partie de la zone dans laquelle les lèvres d'étanchéité entrent en contact avec celle-ci.

    본 발명의 일 실시예에 따르면, 차량의 휠을 차체에 회전 가능하게 장착하여 지지하는 차량용 휠베어링이 제공된다. 본 발명의 일 실시예에 따른 차량용 휠베어링은, 차량의 휠과 함께 회전하는 회전요소와; 차체에 장착되어 고정되는 비회전요소와; 회전요소와 비회전요소 사이에 개재되는 복수의 전동체와; 회전요소와 비회전요소 사이에 장착되어 외부 이물질의 유입을 방지하는 씰링부재를 포함할 수 있다. 본 발명의 일 실시예에 따르면, 씰링부재는 휠베어링의 회전요소와 비회전요소 중 어느 하나에 장착되는 제1 부재와; 휠베어링의 회전요소와 비회전요소 중 다른 하나에 장착되는 제2 부재를 포함할 수 있다. 본 발명의 일 실시예에 따르면, 씰링부재의 제1 부재(600)는 제1 프레임과 제1 프레임에 부착된 탄성 씰링부를 포함할 수 있고, 씰링부재의 제2 부재는 제2 프레임과 제2 프레임에 부착된 탄성 부재를 포함할 수 있다. 본 발명의 일 실시예에 따르면, 탄성 씰링부는 씰링부재의 제2 부재에 접촉하여 씰링을 수행하는 하나 이상의 씰링립을 포함할 수 있고, 제2 부재는 씰링립이 접촉되는 영역의 전부 또는 일부에 요철부를 구비할 수 있다.
