PROBLEM TO BE SOLVED: To provide a working vehicle whose travelling vehicle body can travel straight-forward more stably, and which can improve operation accuracy.SOLUTION: A working vehicle includes: a travelling vehicle body 2 to whose rear part a ground working device 50 for performing work in a farm field can be attached a steering member 32 for receiving an operation for steering a travelling wheel 4 of the travelling vehicle body 2 a position information acquisition device 120 for acquiring position information on the travelling vehicle body 2 an operation amount detection member 112 for detecting an operation amount for the steering member 32 an automatic steering device 110 for steering the travelling wheel 4 and keeping a travelling direction of the travelling vehicle body 2 in a straight-forward travelling direction based on the position information acquired by the position information acquisition device 120 and a control device 150 for controlling the automatic steering device 110. The control device 150 does not reflect the operation for the steering member 32 in the steering of the travelling wheel 4 if it is determined that the travelling vehicle body 2 is travelling straight-forward from the position information acquired by the position information acquisition device 120.SELECTED DRAWING: Figure 9COPYRIGHT: (C)2017,JPO&INPIT【課題】行車体がより安定して直進走行することができ、作業精度を向上させることのできる作業車両を提供すること。【解決手段】圃場での作業を行う対地作業装置50を後部に取り付け可能な走行車体2と、走行車体2の走行輪4を操舵する操作を受け付ける操舵部材32と、走行車体2の位置情報を取得する位置情報取得装置120と、操舵部材32に対する操作量を検出する操作量検出部材112と、位置情報取得装置120が取得した位置情報に基づき、走行輪4を操舵して走行車体2の走行向きを直進方向に維持する自動操舵装置110と、自動操舵装置110を制御する制御装置150とを備える。制御装置150は、位置情報取得装置120が取得した位置情報から走行車体2が直進していると判定した場合、操舵部材32に対する操作を走行輪4の操舵に反映しない。【選択図】図9
