To provide a hub unit with steering function in which, auxiliary steering according to a travel state can be performed on a left wheel and a right wheel independently, for improving maneuver ability of a vehicle, and for improving stability and safety of travel and improving fuel economy, and in which a wheel angle can be correctly changed, and a vehicle comprising the same.SOLUTION: A hub unit 1 with steering function comprises: a hub unit body 2; a unit support member for rotatably supporting the hub unit body 2 around an auxiliary steering shaft center; and an auxiliary steering actuator 5 for rotating and driving the hub unit body 2. The auxiliary steering actuator 5 comprises: a motor 26; and a linear motion mechanism 25 for converting rotation output of the motor 26 into linear motion. The linear motion mechanism 26 comprises: a feed screw mechanism 30 coupled to the hub unit body 2; a rotation support bearing 31 for rotating and supporting the feed screw mechanism 30; and pre-load application means 33 for applying pre-load equal to or more than reaction force input from outside to the rotation support bearing 31.SELECTED DRAWING: Figure 2

    【課題】走行状況に応じた補助的な転舵が左右輪独立で行えて、車両の運動性能を向上させ、走行の安定・安全性の向上と燃費の改善を図ることが可能となり、また車輪角度を正確に変化させることができる転舵機能付ハブユニットおよびそれを備えた車両を提供する。【解決手段】この補助転舵機能付ハブユニット1は、ハブユニット本体2と、ハブユニット本体2を補助転舵軸心回りに回転自在に支持するユニット支持部材と、ハブユニット本体2を回転駆動させる補助転舵用アクチュエータ5とを備える。補助転舵用アクチュエータ5は、モータ26と、モータ26の回転出力を直線動作に変換する直動機構25とを有する。直動機構26は、ハブユニット本体2に連結された送りねじ機構30との送りねじ機構30を回転支持する回転支持軸受31と、回転支持軸受31に外部から入力される反力以上の予圧を与える予圧付与手段33とを有する。【選択図】図2
