PROBLEM TO BE SOLVED: To provide a working vehicle that can perform automatic straight advancing travel by holding a steering member in a straight advancing position, and can automatically correct a traveling direction when a machine body inclines.SOLUTION: The working vehicle includes: steering wheels 10 provided at a traveling vehicle body 2 the steering member 34 for operating the steering wheels 10 and an inclination detecting member 101 provided at the traveling vehicle body 2 to detect the inclination of the machine body. When the inclination detecting member 101 detects a lateral inclination, the steering member 34 is operated to correct the traveling direction of the traveling vehicle body 2. The working vehicle also includes an operation switching member 103 switched into a free state of operating the steering member 34 and into a holding state of holding the steering member 34 in the straight advancing position. Even when the operation switching member 103 is operated into the holding state, if the inclination detecting member 101 detects the inclination of the machine body, the hold of the steering member 34 is released and operated to the opposite side to the inclining direction.COPYRIGHT: (C)2013,JPO&INPIT【課題】操舵部材を直進位置に保持して自動直進走行を行なうことができると共に、機体が傾斜すると自動的に進行方向を修正することのできる作業車両を提供する。【解決手段】走行車体2に操舵輪10を設け、操舵輪10を操作する操舵部材34を設け、走行車体2に機体の傾斜を検出する傾斜検知部材101を設け、傾斜検知部材101が左右方向の傾斜を検知すると操舵部材34を操作して走行車体2の進行方向を補正する作業車両において、操舵部材34を操作自在な自由状態と、操舵部材34を直進位置に保持する保持状態に切り替える操作切替部材103を設け、操作切替部材103を保持状態に操作していても傾斜検知部材101が機体の傾斜を検知すると、操舵部材34の保持を解除して傾斜方向の反対側に操作する構成とする。【選択図】 図9
