PROBLEM TO BE SOLVED: To provide a wheel bearing device with a generator which is raised in a design freedom, secures an installation space of a generator, and is increased in a power generation capacity by the upsize of a field component.SOLUTION: An annular salient part 21 extending to an axial direction is formed at a side face 2c of a vehicle body attachment flange 2b of an outer member 2 at an inner side, a stator 23 which constitutes a generator 30 is attached into an annular space 22 which is formed between the salient part 21 and an external peripheral face 2d of the outer member 2, and a permanent magnetic 29 is attached to a flange-shaped rotor case 31 which extends to the outside of a radial direction from a shoulder part 17 of an outside joint member 12, and is integrally formed. The permanent magnetic is oppositely arranged at the stator 23 via an air gap in the axial direction.SELECTED DRAWING: Figure 2

    【課題】設計自由度が高くなると共に、発電機の設置スペースを確保し、界磁部品のサイズアップにより発電容量の増大を図った発電機付き車輪用軸受装置を提供する。【解決手段】外方部材2の車体取付フランジ2bのインナー側の側面2cに軸方向に延びる環状の突出部21が形成され、この突出部21と外方部材2の外周面2dとの間に形成される環状空間22に発電機30を構成するステータ23が装着されると共に、外側継手部材12の肩部17から径方向外方に延びて一体に形成されたフランジ状のロータケース31に永久磁石29が装着され、軸方向のエアギャップを介してステータ23に対向配置されている。【選択図】図2
