PROBLEM TO BE SOLVED: To avoid great restriction of a detection range of a sensor caused by rise and fall of a work device.SOLUTION: A work vehicle has a traveling machine body 7, a work device 12 connected liftably to the traveling machine body 7, an automatic traveling unit 2 for allowing the traveling machine body 7 to travel automatically, and an object detection unit 101 in which the arrangement side of the work device 12 in the periphery of the traveling machine body 7 is set as an object detection range C. The object detection unit 101 has a first detection sensor 105 installed on an upper side structure 7A of the traveling machine body 7, and a second detection sensor 106 installed on a lower side structure 7B of the traveling machine body 7.SELECTED DRAWING: Figure 7COPYRIGHT: (C)2020,JPO&INPIT【課題】作業装置の昇降によってセンサの検出範囲が大きく制限されることを回避する。【解決手段】作業車両において、走行機体７と、走行機体７に昇降可能に連結された作業装置１２と、走行機体７を自動走行させる自動走行ユニット２と、走行機体７の周囲のうちの作業装置１２の配置側が物体検知範囲Ｃに設定された物体検知ユニット１０１とを有し、物体検知ユニット１０１は、走行機体７の上側構造体７Ａに設置される第１検知センサ１０５と、走行機体７の下側構造体７Ｂに設置される第２検知センサ１０６とを有している。【選択図】図７
