To provide a work vehicle capable of suppressing fruitless work travel caused by taking a too much overlap.SOLUTION: The work vehicle includes: a work unit for prescribing a work width； a travel route setup section that sets a plurality of travel routes RL1 and RL2 extending parallel to each other at a route interval apart, the route interval determined on the basis of the work width W and an overlap value L preset on both sides of the work width W； a displacement value calculation section that calculates a displacement value δ when the work vehicle is displaced from the travel route RL1 as a calculated travel target of an own vehicle to the already-worked area side； a correction value calculation section that calculates a difference value d between the overlap value and the displacement value and defines a value not exceeding the difference value d as a correction value； and a travel route displacing section that displaces the travel route RL2 set to the unworked area to the unworked area side on the basis of the correction value.SELECTED DRAWING: Figure 6【課題】オーバーラップの取り過ぎによる無駄な作業走行を抑制できる作業車を提供する。【解決手段】作業車は、作業幅を規定する作業装置と、作業幅Ｗと作業幅Ｗの両側に予め設定されたオーバーラップ値Ｌとに基づいて決定される経路間隔をあけて平行に延びる複数の走行経路ＲＬ１、ＲＬ２を設定する走行経路設定部と、算出された自車位置が走行目標となっている走行経路ＲＬ１から既作業領域側に位置ずれしている際の位置ずれ値δを算出する位置ずれ値算出部と、オーバーラップ値と位置ずれ値との差分値ｄを求め、差分値ｄを超えない値を修正値とする修正値算出部と、未作業領域に設定された走行経路ＲＬ２を、修正値に基づいて未作業領域側に変位させる走行経路変位部とを備えている。【選択図】図６
