To provide a travel control device and a work vehicle capable of suppressing a negative effect of erroneous detection of an obstacle.SOLUTION: A travel control device includes: an obstacle detection unit 10 provided to a work vehicle 100 for detecting an obstacle present around the work vehicle； nullification instruction means 23 for giving a nullification instruction to nullify the obstacle detection by the obstacle detection unit 10； and a notification unit 50 for executing notification based on the detection of the obstacle by the obstacle detection unit 10. When the nullification instruction is operated, notification by the notification unit 50 is interrupted.SELECTED DRAWING: Figure 1【課題】障害物の誤検出による弊害を抑制することが可能な走行制御装置及び作業車を提供する。【解決手段】作業車両１００に備えられ、作業車両の周囲に存在する障害物を検出する障害物検知部１０と、障害物検出部１０による障害物検出を無効化する無効化指示を行う無効化指示手段２３と、障害物検知部１０による障害物の検知に基づく報知を行う報知部５０と、を備え、無効化指示が操作されると、報知部５０による報知を中断する。【選択図】図１
