PROBLEM TO BE SOLVED: To provide a two front-wheel steering bicycle which can hold an upright attitude without falling even when a vehicle is in a stop state, enables stable curve traveling by mechanically tilting a vehicle body in a turning direction according to steering of a handle, and thereby allows an elderly person to easily ride the bicycle.SOLUTION: A linear bushing 22 incorporating a slide shaft 23 is fixed to a front hub 21 attached to a swing arm 31. A pitman arm 41 integrated with a connection plate 26 is fixed to a steering shaft 13. A rod end Brg25 connected to the connection plate 26 and the slide shaft 23 are coupled to each other. The pitman arm 41 is coupled to a knuckle arm 45L via a link ball Brg46 and a connection rod 47S. The rod end Brg25 and the pitman arm 41 rotate to the left by steering a handle 11 to the left. A vehicle body 1 can be mechanically tilted in a turning direction simultaneously as front wheels 15L, 15R are directed leftward via a connecting rod 47L.SELECTED DRAWING: Figure 7

    【課題】停車状態の乗車でも転倒することなく、直立姿勢が保持でき、ハンドルの操舵に応じて旋回方向へ機械的に車体を傾斜させ、安定したカーブ走行を可能にして、高齢者が乗り易い前二輪操舵の自転車にする。【解決手段】揺動アーム31に取付けられたフロントハブ21に、スライド軸23が組み込まれたリニアブシュ22が固定され、操向軸13に接続板26と一体化したピットマンアーム41が固着され、接続板26に接続されたロッドエンドBrg25と、スライド軸23が連結され、ピットマンアーム41がリンクボールBrg46と接続棒47Sを介して、ナックルアーム45Lに連結され、ハンドル11の左方への操舵で、ロッドエンドBrg25と、ピットマンアーム41が左方に回動し、接続棒47Lを介して前輪15L,15Rが左方に向くのと同時進行で、車体1が旋回方向へ機械的に傾斜が可能な構成とする。【選択図】図7
