PROBLEM TO BE SOLVED: To provide a work vehicle capable of controlling automatic steering of a travel machine body.SOLUTION: A work vehicle comprises: a travel machine body C having a travel unit A； a reception device 63 for acquiring positional information by a satellite positioning system； and a control part for, based on the positional information, controlling a steering unit U so that the travel machine body C travels along a target line. The work vehicle further comprises a support member 31 for supporting the reception device 63, and the support member 31 supports the reception device 63 so as to be changed in a state, between a use state, and a storage state in which, the reception device 63 is positioned on a position lower than that in the use state.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】走行機体の自動操向制御が可能な作業車を提供する。【解決手段】走行装置Ａを有する走行機体Ｃと、衛星測位システムにより位置情報を取得する受信装置６３と、位置情報に基づいて、走行機体Ｃが目標ラインに沿って走行するように、操向ユニットＵを制御する制御部と、が備えられ、受信装置６３を支持可能な支持部材３１が設けられ、支持部材３１が、使用状態と、使用状態よりも低い箇所に受信装置６３を位置させた格納状態と、に状態変更可能に受信装置６３を支持する。【選択図】図１
