To provide a bearing device for a wheel with a power generator which does not deteriorates a function of a bearing for the wheel, secures a motor volume of the power generator, rigidly fixes a stator and is excellent in maintenance performance, and to provide a vehicle provided with the bearing device for the wheel with the power generator.SOLUTION: In a bearing device 1 for a wheel with a power generator, the whole power generator has a smaller diameter than that of an outer circumferential part 12b of a brake rotor 12 and the whole except a fitting part to a hub flange 7 of the power generator 3 is located in an axial direction range L1 between a car body fitting surface of an inboard side of a bearing 2 for the wheel and the hub flange 7. A fixed ring has a fitting flange 20 which includes a flange part 20b located at the inboard side on an outer circumferential surface of an outer ring 2 and at the inboard side than a knuckle 8. A stator retention member 24 which is brought into contact with an inner circumferential surface and an inboard side end surface of a stator 18 and retains the stator 18 and a fastening bolt 22 which integrally fastens the stator retention member 24, the knuckle 8 and the fitting flange 20 are provided.SELECTED DRAWING: Figure 1
【課題】車輪用軸受の機能を劣化させることなく、且つ発電機のモータ体積を確保し、且つステータを強固に固定すると共にメンテナンス性に優れた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】発電機付き車輪用軸受装置1は、発電機全体が、ブレーキロータ12の外周部12bよりも小径で、且つ、発電機3のハブフランジ7への取付部を除く全体が、車輪用軸受2のインボード側の車体取り付け面とハブフランジ7との間の軸方向範囲L1に位置する。固定輪は、外輪2の外周面におけるインボード側で且つナックル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を有する。ステータ18の内周面およびインボード側端面に接してステータ18を保持するステータ保持部材24と、ステータ保持部材24とナックル8と取付用フランジ20とを一体に締結する締結ボルト22とを備える。【選択図】図1
