To provide a wheel support rolling bearing which can be reduced in a size.SOLUTION: A wheel support rolling bearing 1 comprises an inner ring 10 fixed to a wheel, an outer ring 40 fixed to a vehicle body, and a plurality of needle-shaped rollers 50 rollingly arranged between the inner ring 10 and the outer ring 40. The inner ring 10 has a first raceway surface 11 which opposes the outer ring 40 in a radial direction, and a second raceway surface 12 and a third raceway surface 13 which oppose the outer ring 40 in an axial direction. The second raceway surface 12 is located inside the outer ring 40 in the axial direction, and the third raceway surface 13 is located outside the outer ring 40 in the axial direction. The plurality of needle-shaped rollers 50 include a plurality of first needle-shaped rollers 51 arranged between the first raceway surface 11 and the outer ring 40, a plurality of second needle-shaped rollers 52 arranged between the second raceway surface 12 and the outer ring 40, and a plurality of third needle-shaped rollers 53 arranged between the third raceway surface 13 and the outer ring 40.SELECTED DRAWING: Figure 1

    【課題】小型化を図ることができる車輪支持用転がり軸受を提供する。【解決手段】車輪支持用転がり軸受1は、車輪に固定される内輪10と、車体に固定される外輪40と、内輪10と外輪40との間に転動可能に配置された複数の針状ころ50と、を備える。内輪10は、径方向において外輪40と向かい合う第1軌道面11と、軸方向において外輪40と向かい合う第2軌道面12及び第3軌道面13と、を有する。第2軌道面12は、外輪40に対して軸方向における内側に位置しており、第3軌道面13は、外輪40に対して軸方向における外側に位置している。複数の針状ころ50は、第1軌道面11と外輪40との間に配置された複数の第1針状ころ51と、第2軌道面12と外輪40との間に配置された複数の第2針状ころ52と、第3軌道面13と外輪40との間に配置された複数の第3針状ころ53と、を含む。【選択図】図1
