PROBLEM TO BE SOLVED: To provide a work vehicle capable of performing appropriate automatic steering control by setting up a target line at a position tailored to an operator's sensation without any labor.SOLUTION: The work vehicle includes: an automatic steering-control part capable of changing over between an automatic-steering on state of causing a travel device A to automatically steer a travel machine body C such that the travel machine body travels along a target line LM on the basis of positioning information including position information acquired by a receiver 63, and an automatic-steering off state of not automatically steering the travel device A； a changeover operation tool capable of changing over the automatic steering control part from the automatic-steering off state to the automatic-steering on state on the basis of a manual operation； and a reference setup part setting up the target line LM on a correction position M1 that is calculated on the basis of a value obtained by adding a front-side clearance B1 of the travel machine body C to a position of the receiver 63 when it is changed over from the automatic-steering off state to the automatic-steering on state by the changeover operation tool.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2018,JPO&INPIT【課題】手間をかけずにオペレータの感覚に適合した位置に目標ラインを設定して好適な自動操向制御を行うことができる作業車を提供する。【解決手段】受信装置６３で取得された位置情報を含む測位情報に基づいて目標ラインＬＭに沿って走行機体Ｃを走行させるように走行装置Ａを自動操向する自動操向オン状態と、走行装置Ａを自動操向しない自動操向オフ状態と、を切り換え可能な自動操向制御部と、自動操向制御部を自動操向オフ状態から自動操向オン状態へ手動操作に基づいて切り換え操作可能な切換操作具と、目標ラインＬＭを、切換操作具により自動操向オフ状態から自動操向オン状態に切り換えられた際の受信装置６３の位置に走行機体Ｃの前方側の離間距離Ｂ１を加算した値に基づいて求められる補正位置Ｍ１上に設定する基準設定部と、が備えられている。【選択図】図６
