To provide a work vehicle which, when the advancing direction of the traveling vehicle body deviates from a reference line, narrows the range in which an already worked position becomes disturbed and suppresses a deviation of the work vehicle from the worked position.SOLUTION: The traveling vehicle body of the work vehicle is provided with: a work arrangement for performing work in a farm field； a steering member for steering traveling wheels of the traveling vehicle body； an automatic steering device for operating the steering member to cause the traveling vehicle body to automatically travel on a travel route； a control device for operating the automatic steering device to cause the traveling vehicle body to travel along a preset travel route； and a direction detection member for detecting the direction of the traveling vehicle. If the direction of the machine body detected by the direction detection member is different from the preset travel route by a predetermined value or more, the control device moves the traveling vehicle body to a direction in which work is not yet performed by the work arrangement such that the steering member is steered to a direction in which the preset travel route is followed.SELECTED DRAWING: Figure 5【課題】 走行車体の進行方向が基準線からずれた際、既作業位置を荒らす範囲を狭めると共に、作業装置の作業位置のずれの発生を抑える作業車両を提供する。【解決手段】 走行車体に圃場内で作業を行う作業装置を設け、走行車体の走行輪を操舵する操舵部材を設け、操舵部材を操作して走行車体を走行経路上で自動走行させる自動操舵装置を設け、自動操舵装置を作動させて走行車体を設定された走行経路に沿って走行させる制御装置を設けた作業車両において、走行車体の向きを検知する方向検知部材を設け、制御装置は、方向検知部材が検知する機体の向きと設定された走行経路が所定値以上異なると、作業装置による作業済みでない方向に走行車体を移動させ、設定された走行経路に向かう方向に操舵部材を操舵させる構成とする。【選択図】図５
