PROBLEM TO BE SOLVED: To calculate a shape of a gate passage, and easily and accurately calculate a working ground region except the gate passage.SOLUTION: A travel route generating device for a working vehicle working in a working ground partitioned by a boundary comprises: a start point registering unit 621 which registers a location of a first edge point on a boundary side of a gate passage as a start point Ps； a lapse point registering unit 622 which registers a location of a shape feature point defining a shape of the working ground as a lapse point P1, P2, or P3； an end point registering unit 623 which registers a location of a second edge point facing the first edge point on the boundary side of the gate passage as an end point Pe； a basic shape calculating unit 624 which calculates a working ground basic shape by linking the start point Ps, the lapse points P1, P2, and P3, and the final point Pe； and a gate passage information generating unit 625 which generates gate passage information with a square in which the start point Ps and the end point Pe serve as an opposite vertex as the shape of the gate passage.SELECTED DRAWING: Figure 4【課題】出入口通路の形状を算出して、出入口通路を除く作業地領域を、簡単かつ正確に算出すること。【解決手段】境界によって区画された作業地を作業する作業車のための走行経路生成装置は、出入口通路の境界側の第１端点を始点Ｐｓとして位置登録する始点登録部６２１と、作業地の形状を規定する形状特徴点を経過点Ｐ１、Ｐ２、Ｐ３として位置登録する経過点登録部６２２と、出入口通路の境界側の、第１端点と対向する第２端点を終点Ｐｅとして位置登録する終点登録部６２３と、始点Ｐｓと経過点Ｐ１、Ｐ２、Ｐ３と終点Ｐｅとを結ぶことで作業地基本形状を算出する基本形状算出部６２４と、始点Ｐｓと終点Ｐｅとを対頂点とする四角形を出入口通路の形状として出入口通路情報を生成する出入口通路情報生成部６２５とを備える。【選択図】図４
