The present invention provides a work vehicle capable of reminding a worker when the machine body arrived at a target position where operations to be performed are unnecessary and the machine body is about to leave the target position. The work vehicle is provided with a steering part configured to steer the machine body； a position information acquisition device configured to acquire the position coordinate of the machine body； and an automatic straight moving device configured to actuate the steering part to enable the machine body to move straight. In the work vehicle, a control part is provided to obtain a reference position served as the reference to straight moving, delete the obtained reference position and turn on or turn off the automatic straight moving device. When the control part is operated toward a first direction, the reference position is obtained； when the control part is operated toward a second direction, the automatic straight moving device is turned on or turned off.本發明提供一種作業車輛，在機體接近目標位置時，在進行不必要的作業、行駛之前能夠提醒作業者。作業車輛，係具備：對機體進行轉向操作的轉向部件；取得機體的位置座標的位置資訊取得裝置；以及使轉向部件動作而使機體直行行駛的自動直行裝置，在作業車輛中，由一個操作部件進行作為直行行駛的基準之基準位置的取得、已取得的基準位置之刪除和自動直行裝置的開啟或關閉，若將操作部件向第一方向操作則取得基準位置，若將操作部件向第二方向操作則自動直行裝置被開啟或關閉。
