To upgrade the freedom in designing a steering characteristic of a leaning vehicle having two front wheels that are steering wheels.SOLUTION: A two front-wheel counter-steering leaning vehicle 1 includes a body frame 21, a left front wheel 32, a right front wheel 31, a rear wheel 4, a leaning mechanism 5, a counter-steering mechanism 7, and a leaning responsiveness adjustment mechanism 74. The leaning mechanism 5 includes an arm 51 that is supported to be turnable relative to the body frame 21. Since the arm 51 is turned relative to the body frame 21, the body frame 21 leans in a vertical direction of the vehicle 1. The counter-steering mechanism 7 mechanically transmits a left turn of a handlebar 23, and mechanically transmits a right turn of the handlebar 23. The leaning responsiveness adjustment mechanism 74 controls a motor 421 in response to a command value dependent on a time differential of a physical quantity stemming from a rider's action that affects leaning of the body frame 21, and thus adjusts the responsiveness to the leaning in a lateral direction of the vehicle of the body frame 21.SELECTED DRAWING: Figure 7

    【課題】前二輪の操舵輪を備えるリーン車両において、操縦特性の設計自由度を向上させる。【解決手段】前二輪逆操舵リーン車両1は、車体フレーム21と、左前輪32と、右前輪31と、後輪4と、リーン機構5と、逆操舵機構7と、リーン応答性調整機構74とを備える。リーン機構5は、車体フレーム21に対して回転可能に支持されるアーム51を含む。アーム51が車体フレーム21に対して回転することにより、車体フレーム21が車両1の上下方向に対してリーンする。逆操舵機構7は、ハンドル23の左回転を機械的に伝達し、ハンドル23の右回転を機械的に伝達する。リーン応答性調整機構74は、車体フレーム21のリーンに影響を与えるライダーの動作に起因して発生する物理量の時間微分に基づく指令値でモータ421を制御することにより、車体フレーム21の車両の左右方向のリーンの応答性を調整する。【選択図】図7
