To provide a three-row wheel vehicle which is so improved that a front wheel rises and can easily ride on a step and so on by inclining the front wheel in front-rise.SOLUTION: A three-row wheel vehicle 10 has a front wheel 16 arranged in a cross direction, a central wheel 18 and a rear wheel 20. The vehicle has: a front wheel support arm 24 which is so connected to a vehicle body 14 as to be capable of swinging around a first pivot axis 30A in a cross direction, and rotatably supports the front wheel at a lower end part; a central wheel support arm 26 which is so connected to the vehicle body as to be capable of swinging around a second pivot axis 34A in a vertical direction, and rotatably supports the central wheel; a motion transmission link 50 which transmits swinging of the front wheel support arm to the central wheel support arm. The motion transmission link converts swinging of the front wheel support arm around the first pivot axis in a direction of backward movement of the front wheel into pivotal movement around the second pivot axis in a lowering direction of the central wheel, and transmits the same to the central wheel support arm.SELECTED DRAWING: Figure 1

    【課題】車両を前上がりに傾斜させることにより、前輪が上昇して段差などへ容易に乗り上げることができるよう改良された三列車輪車両を提供する。【解決手段】前後方向に配列された前輪16、中央輪18及び後輪20を有する三列車輪車両10。車両は、第一の枢軸線30Aの周りに前後方向に揺動可能に車体14に連結され且つ下端部にて前輪を回転可能に支持する前輪支持アーム24と、第二の枢軸線34Aの周りに上下方向に枢動可能に車体に連結され中央輪を回転可能に支持する中央輪支持アーム26と、前輪支持アームの揺動を中央輪支持アームへ伝達する運動伝達リンク50と、を有し、運動伝達リンクは、前輪が後方へ移動する方向の第一の枢軸線の周りの前輪支持アームの揺動を、中央輪が下降する方向への第二の枢軸線の周りの枢動に変換して中央輪支持アームへ伝達するよう構成されている。【選択図】図1
