A rolling bearing for supporting a wheel is provided with an inner ring fixed to a wheel, an outer ring fixed to a vehicle body, and a plurality of needle rollers arranged between the inner ring and the outer ring so as to be capable of rolling. The inner ring has a first raceway surface facing the outer ring in the radial direction, and a second raceway surface and a third raceway surface facing the outer ring in the axial direction. The second track surface is located on the inner side in the axial direction relative to the outer ring, and the third track surface is located on the outer side in the axial direction relative to the outer ring. The plurality of needle-like rollers include a plurality of first needle-like rollers disposed between the first raceway surface and the outer ring, a plurality of second needle-like rollers disposed between the second raceway surface and the outer ring, and a plurality of third needle-like rollers disposed between the third raceway surface and the outer ring.
车轮支承用滚动轴承具备固定于车轮的内圈、固定于车身的外圈和能够滚动地配置在内圈与外圈之间的多个针状滚子。内圈具有在径向上与外圈相对的第一轨道面、在轴向上与外圈相对的第二轨道面及第三轨道面。第二轨道面相对于外圈位于轴向上的内侧,第三轨道面相对于外圈位于轴向上的外侧。多个针状滚子包括配置在第一轨道面与外圈之间的多个第一针状滚子、配置在第二轨道面与外圈之间的多个第二针状滚子、和配置在第三轨道面与外圈之间的多个第三针状滚子。
