To provide a bearing device for wheel with a generator which has assemblability equivalent to a conventional bearing for wheel and can extend a mounting space of a generator than a conventional bearing for wheel, and to provide a vehicle provided with the bearing device for wheel with the generator.SOLUTION: A bearing device 1 for wheel with a generator includes: a bearing 2 for vehicle having an outer ring 4 and an inner ring 5 which has a hub flange 7, is rotatably supported by the outer ring 4 via a rolling body 6 and has the wheel of the vehicle and a brake rotor 12 mounted on a hub flange 7; a stator 19 mounted on the outer ring 4; and a generator 3 having a rotor 19 mounted on the inner ring 5. The outer ring 4 has a flange 20 for fitting including a flange part 20b which is provided on the outer peripheral surface of the outer ring 4 and is positioned close to the inboard side of a knuckle 8, and the flange 20 for fitting is composed separately from the outer ring 4 and is fastened to the knuckle 8.SELECTED DRAWING: Figure 1
【課題】従来の車輪用軸受と同等の組み付け性を有し、且つ、従来の車輪用軸受よりも発電機の実装空間を拡張することができる発電機付き車輪用軸受装置およびこの発電機付き車輪用軸受装置を備えた車両を提供する。【解決手段】この発電機付き車輪用軸受装置1は、外輪4、およびハブフランジ7を有し外輪4に転動体6を介して回転自在に支持されてハブフランジ7に車両の車輪およびブレーキロータ12が取付けられる内輪5を有する車輪用軸受2と、外輪4に取付けられたステータ19、および内輪5に取付けられたロータ19を有する発電機3とを備える。外輪4は、この外輪4の外周面に設けられ且つナックル8よりもインボード側に位置するフランジ部20bを含む取付用フランジ20を有し、この取付用フランジ20は、外輪4と別体に構成され、ナックル8に締結されている。【選択図】図1
