According to one embodiment of the present invention, provided is a wheel bearing that supports a wheel of a vehicle by rotatably mounting thereof on a vehicle body. The wheel bearing according to one embodiment of the present invention may comprise: an outer ring part that supports an electrically-driven body from the outside in a radial direction; an inner ring part that supports the electrically-driven body from the inside in the radial direction; and the electrically-driven body disposed in double rows axially spaced apart between the outer ring part and the inner ring part. According to one embodiment of the present invention, the outer ring part may comprise: a first outer ring part having a raceway surface formed, on the inner surface, for the electrically-driven body of a first row; a second outer ring part having a raceway surface formed, on the inner surface, for the electrically-driven body of a second row; and a spacer disposed between the first outer ring part and the second outer ring part. According to one embodiment of the present invention, the spacer may be configured such that one axial cross-section is coupled to the first outer ring part and the other axial cross-section is coupled to the second outer ring part, so that the first outer ring part and the second outer ring part are formed in one integrated structure through the spacer.

    본 발명의 일 실시예에 따르면, 차량의 휠을 차체에 회전 가능하게 장착하여 지지하는 휠베어링이 제공된다. 본 발명의 일 실시예에 따른 휠베어링은 전동체를 반경방향 외측에서 지지하는 외륜부와; 전동체를 반경방향 내측에서 지지하는 내륜부와; 외륜부와 내륜부 사이에서 축방향으로 이격되어 복열로 배치되는 전동체를 포함할 수 있다. 본 발명의 일 실시예에 따르면, 외륜부는 내주면에 제1 열의 전동체를 위한 궤도면이 형성된 제1 외륜부와; 내주면에 제2 열의 전동체를 위한 궤도면이 형성된 제2 외륜부와; 제1 외륜부와 제2 외륜부 사이에 배치되는 스페이서를 포함할 수 있다. 본 발명의 일 실시예에 따르면, 스페이서는 일측 축방향 단면이 제1 외륜부에 결합되고 타측 축방향 단면이 제2 외륜부에 결합되어, 제1 외륜부와 제2 외륜부가 스페이서를 통해 하나의 일체형 구조로 형성되도록 구성될 수 있다.
