PROBLEM TO BE SOLVED: To provide a working vehicle which can prevent the movement of the working vehicle which is not intended by a worker or the like when autonomous traveling is started and so fourth.SOLUTION: A working vehicle comprises: a transmission mechanism for transmitting the power of a drive source 6 arranged at a traveling machine body 2 to traveling devices 3, 4； a brake part which can switch the working vehicle to a brake state that brake forces are made to act on the traveling devices 3, 4, and a non-brake state that the brake forces are not made to act on the traveling devices 3, 4； a stop state maintenance part which can switch the traveling machine body 2 to a first state for maintaining the traveling machine body to a stop state, and a second state for releasing the maintenance of the stop state of the traveling machine body 2； and a control part which can operate the traveling devices 3, 4 by controlling the transmission mechanism and the stop state maintenance part according to a traveling start signal. When the brake part is in a non-brake state, and the stop state maintenance part is in the first state, the control part switches the stop state maintenance part to the second state from the first state according to the traveling start signal, and operates the traveling devices 3, 4 by controlling the transmission mechanism.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】自律走行を開始させる場合等に、作業者等が意図していない作業車両の移動を防止することができる作業車両の提供。【解決手段】走行機体２に備えられる駆動源６の動力を走行装置３，４に伝達する伝達機構と、走行装置３，４に制動力を作用させる制動状態と走行装置３，４に制動力を作用させない非制動状態とに切替可能な制動部と、走行機体２を停止状態に維持する第１の状態と走行機体２の停止状態の維持を解除する第２の状態とに切替可能な停止状態維持部と、走行開始信号に応じて伝達機構及び停止状態維持部を制御して走行装置３，４を作動させることが可能な制御部とを備え、制御部は、制動部が非制動状態であり、且つ、停止状態維持部が第１の状態である場合に、走行開始信号に応じて停止状態維持部を第１の状態から第２の状態に切り替え、且つ、伝達機構を制御して走行装置３，４を作動させる。【選択図】図１
