PROBLEM TO BE SOLVED: To provide an automatic-travel working machine capable of automatically traveling even on an inclined slope face without any deviation from a travel route by highly accurately receiving a positioning signal from a navigation satellite.SOLUTION: The automatic-travel working machine includes: a travel machine body 1； a positioning receiver 4 for receiving a positioning signal from a navigation satellite； an inclination detection part detecting an inclination of the travel machine body 1 and outputting inclination angle information； an inclination angle determination part determining the inclination angle on the basis of the inclination angle information； and a rotation control mechanism 5 rotating the positioning receiver 4 at one or more degree of freedom, where the rotation control mechanism 5 horizontally retains the positioning receiver 4 on the basis of the inclination angle.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2019,JPO&INPIT【課題】傾斜した法面であっても、航法衛星から測位信号を精度よく受信し、走行経路を逸脱せずに自動走行が可能な自動走行作業機を提供する。【解決手段】走行機体１と、航法衛星から測位信号を受信する測位受信機４と、測位信号に基づいて、走行経路に沿って自動走行する自動走行制御装置と、走行機体１の傾きを検出して傾斜角情報を出力する傾斜検出部と、傾斜角情報に基づいて傾斜角度を決定する傾斜角度決定部と、測位受信機４を一以上の自由度で回転する回転制御機構５と、が備えられ、回転制御機構５は、傾斜角度に基づいて測位受信機４を水平に保持する。【選択図】図６
