PROBLEM TO BE SOLVED: To provide a work vehicle having an automatic mode in which a steering handle is automatically operated by various sensors, control equipment and a steering unit and a manual mode in which the steering handle is manually operated, provided with switching means by which the modes are switched, and capable of allowing the steering unit to be easily and inexpensively installed thereon.SOLUTION: A steering unit 24 including a drive roller which is driven by abutting on a steering handle 12 is fixed to a further front side than an operation panel 13 which is arranged in front of the steering handle 12, and on which a meter or an operation tool is provided. The steering handle 12 and the drive roller 41 are driven by energizing means 44 which energizes the drive roller 41 in the direction of the steering handle 12 and by switching means 15 which can be arranged at a position where the steering handle 12 abuts on the drive roller 41, and thus, the steering handle 12 is steered.

    【課題】各種センサ、制御機器、操舵ユニットによりステアリングハンドルが自動操作される自動モードと、ステアリングハンドルを手動操作する手動モードとを有し、モードの切換を行う切換手段を設けた作業車両において、前記操舵ユニットを簡易且つ低コストで設置できる作業車両を提供することを課題としている。【解決手段】ステアリングハンドル12と当接し駆動する駆動ローラを含む操舵ユニット24を前記ステアリングハンドル12の前方に配置され且つメータ又は操作具が設けられた操作パネル13のさらに前側に固定し、また、前記ステアリングハンドル12の方向に前記駆動ローラ41を付勢する付勢手段44と、前記ステアリングハンドル12と前記駆動ローラ41が当接する位置に配置できる切換手段15によって、前記ステアリングハンドル12と前記駆動ローラ41を駆動させ、前記ステアリングハンドル12を操舵する。【選択図】図2
