PROBLEM TO BE SOLVED: To highly improve efficiency of a transmission path and improve operability while securing weight reduction and cost reduction in a working vehicle such as a tractor.SOLUTION: A working vehicle includes an engine 5 mounted on a traveling machine body 2, a straight system transmission path having a first continuously variable transmission 500, a turning system transmission path having a second continuously variable transmission 701, left and right traveling units 3 driven on the basis of the resultant force of outputs of the straight system transmission path and the turning system transmission path, an inclination detection sensor 864 for measuring an inclination state of the traveling machine body 2, and a control unit 810 for calculating an inclination angle of the traveling machine body 2 on the basis of a signal from the inclination detection sensor 864. The control unit 810 calculates centrifugal force applied on the inclination detection sensor 864 on the basis of a ratio of the turning to the straight travel for setting the output of the turning system transmission path to the output of the straight system transmission path, and corrects the inclination angle of the traveling machine body 2.SELECTED DRAWING: Figure 21【課題】トラクタのような作業車両において、軽量化及び低コスト化を確保しながら、伝動経路の高効率化とともに操作性の向上を図る。【解決手段】作業車両は、走行機体２に搭載するエンジン５と、第１無段変速装置５００を有する直進系伝動経路と、第２無段変装置７０１を有する旋回系伝動経路と、直進系伝動経路及び旋回系伝動経路の出力の合成力に基づいて駆動する左右の走行部３と、走行機体２の傾斜状態を測定する傾斜検知センサ８６４と、傾斜検知センサ８６４からの信号に基づいて走行機体２の傾斜角度を演算する制御部８１０を備えている。制御部８１０が、直進系伝動経路の出力に対して旋回系伝動経路の出力を設定する旋回／直進比に基づいて傾斜検知センサ８６４にかかる遠心力を算出して、走行機体２の傾斜角度を補正する。【選択図】図２１
