To provide a hub unit with a steering function which can absorb an attachment error of a steering actuator to enable smooth steering of a hub bearing around a steering shaft.SOLUTION: A hub unit 1 with a steering function includes: a hub bearing 8 which rotationally supports a wheel 10; a cylindrical steering shaft part 24 which extends upward and downward from an outer ring 22 provided on an outer peripheral surface of an outer ring 12 of the hub bearing 8; a steering actuator 4 which rotates the hub bearing 8 around an axis AX of the steering shaft part 24; a unit support member 6 which supports the hub bearing 8 at a vehicle body in a manner that the hub bearing 8 can rotate around the axis AX of the steering shaft part 24; and an arm part 28 which protrudes to a vehicle rear from the outer ring 22 and to which the actuator 4 is connected. The actuator 4 has an extendable part 42 which can extend or contract in a direction orthogonal to the axis AX of the steering shaft part 24. The extendable part 42 and the arm part 28 are connected by a joint part 44 having a degree of freedom of two or more directions.SELECTED DRAWING: Figure 1

    【課題】操舵用アクチュエータの取付誤差を吸収でき、ハブベアリングを転舵軸回りに円滑に操舵させることができる操舵機能付ハブユニットを提供する。【解決手段】操舵機能付ハブユニット1は、車輪10を回転支持するハブベアリング8と、ハブベアリング8の外輪12の外周面に設けられたアウターリング22から上方および下方に延びる筒状の転舵軸部24と、転舵軸部24の軸心AX回りにハブベアリング8を回転させる操舵用のアクチュエータ4と、転舵軸部24の軸心AX回りに回転自在にハブベアリング8を車体に対して支持するユニット支持部材6と、アウターリング22から車両後方に突出し、アクチュエータ4が連結されるアーム部28とを備えている。アクチュエータ4は、転舵軸部24の軸心AXに直交する方向に伸縮自在な伸縮部42を有し、伸縮部42とアーム部28が2方向以上の自由度を有する継手部44を介して連結されている。【選択図】図1
