Summary:To provide a work vehicle capable of achieving inexpensively, smooth automatic travel control in turning.SOLUTION: A work vehicle comprises: an obstruction detection mechanism for detecting an obstruction existing in the surrounding of a vehicle body 10; and a controller for performing automatic travel control for causing the vehicle body 10 to travel along a travel route C which is set in advance and includes direct advance routes Cs and a turning route Ct for connecting two direct advance routes Cs, using an obstruction detection result of the obstruction detection mechanism. The controller suppresses use of the obstruction detection result in a detection range A on a front side of the vehicle body 10 and on outside of turning, when the vehicle body 10 is going to turn or turns.SELECTED DRAWING: Figure 9 【課題】旋回時の円滑な自動走行制御を廉価に実現できる作業車両を提供する。【解決手段】車体１０の周辺に存在する障害物の検出を行う障害物検出機構と、直進経路Ｃｓ、および二つの直進経路Ｃｓを接続する旋回経路Ｃｔを含むあらかじめ設定された走行経路Ｃに沿って車体１０を走行させるための自動走行制御を、障害物検出機構の障害物検出結果を利用することにより行うコントローラーと、を備え、コントローラーは、車体１０が旋回しようとするまたは旋回しているとき、車体１０の前側および旋回外側の検出範囲Ａにおける障害物検出結果の利用を抑制する。【選択図】図９
