To set a target travel path according to a desire of a user.SOLUTION: A travel path setting device comprises: a work area setting part for setting a work area R where a work vehicle performs a prescribed work in a travel area S； and a travel path setting part for setting a target travel path P for travel guide for causing the work vehicle to automatically travel, in the travel area S. The travel path setting part comprises: an initial path generation part for generating an initial path P1 based on the travel locus by traveling of the work vehicle in the travel area S； a work path generation part for, based on the initial path P1, generating a plurality of work paths P3 arranged in an arrangement direction X2 orthogonal to an extension direction X1 of the initial path P1 with respect to the initial path P1 in parallel； and a connection path generation part for generating a plurality of connection paths P4 which connect paths adjacent in the arrangement direction on one end side or the other end side of the work area R, out of the initial path P1 and the plurality of work paths P3, in which the target travel path P including the initial path P1, the plurality of work paths P3, and the plurality of connection path P4 is set.SELECTED DRAWING: Figure 5【課題】ユーザの要望に応じた目標走行経路を設定すること。【解決手段】走行領域Ｓ内に作業車両が所定の作業を行うための作業領域Ｒを設定する作業領域設定部と、作業車両を自動走行させるための走行案内用の目標走行経路Ｐを走行領域Ｓ内に設定する走行経路設定部とを備え、走行経路設定部は、走行領域Ｓ内での作業車両の走行による走行軌跡に基づく初期経路Ｐ１を生成する初期経路生成部と、初期経路Ｐ１に基づいて、初期経路Ｐ１に対してその延設方向Ｘ１に直交する並設方向Ｘ２に平行状態で並ぶ複数の作業経路Ｐ３を生成する作業経路生成部と、初期経路Ｐ１及び複数の作業経路Ｐ３のうち、並設方向に隣接する経路を作業領域Ｒの一端側又は他端側にて連結する複数の連結経路Ｐ４を生成する連結経路生成部とを備え、初期経路Ｐ１、複数の作業経路Ｐ３、及び、複数の連結経路Ｐ４を含む目標走行経路Ｐを設定している。【選択図】図５
