To provide a hub unit with a steering function which enables left and right wheels to be controlled at proper steering angles according to a travel state in addition to normal steering and, in this case, enables a moving distance of an output rod of a linear mechanism to be accurately monitored and redundancy secured.SOLUTION: This hub unit 1 with a steering function includes: a hub unit body 2 having a hub bearing 15 for supporting a wheel; a unit support member 3 which is provided at a knuckle 6 of a suspension and supports the hub unit body 2 in a manner that the hub unit body 2 can rotate around a steering axis A as seen in a vertical direction; and a steering actuator 5 which rotates the hub unit body 2. The steering actuator 5 steers through an output rod 25a of a linear mechanism 25 moving forward and rearward. A position sensor 44 which detects a moving distance of the output rod 25a of the linear mechanism 25 is provided. The position sensor 44 has two semiconductor elements for detecting change of a position in one package.SELECTED DRAWING: Figure 2

    【課題】通常の操舵に付加して、走行状況に合わせ左右の車輪を適切な転舵角に制御できるようにする。この場合に、コンパクトな構造で、直動機構の出力ロッドの移動量を正確に、かつ冗長性を確保して監視することができるようにする。【解決手段】この操舵機能付ハブユニット1は、車輪支持用のハブベアリング15を有するハブユニット本体2と、懸架装置のナックル6に設けられてハブユニット本体2を上下方向の転舵軸心A回りに回転自在に支持するユニット支持部材3と、ハブユニット本体2を回転させる操舵用アクチュエータ5とを備える。操舵用アクチュエータ5は、直動機構25の出力ロッド25aが進退することで転舵させる。この直動機構25の出力ロッド25aの移動量を検出する位置センサ44を設ける。この位置センサ44は、位置の変化を検出する半導体素子を1パッケージに2個有する。【選択図】図2
