PROBLEM TO BE SOLVED: To provide a working vehicle capable of preventing an traveling operation from getting stagnant during slewing by installing an operating device that allows a driving force to be supplied to a traveling device that can steer a drive unit during slewing.SOLUTION: Traveling devices 11, 11 and a transmission switching device 300 are installed on a traveling vehicle body 2 in a pair in the horizontal direction. An operating member 34 that slews a traveling vehicle body 2 in the horizontal direction is installed. There is also provided a slewing interlocking mechanism 307 that operates the transmission switching device 300 in the slewing inside to "OFF" side, interlocking with operation of the operating member 34. Additionally, there is also an interlocking operation mechanism 317 that connects the slewing interlocking mechanism 307 with a switching member 305. A transmission operation member 303 is also provided, and the transmission operation member 303 and the switching member 305 are connected through a linking operation member 304.COPYRIGHT: (C)2013,JPO&INPIT【課題】旋回時に駆動力の切れる走行装置に駆動力を供給する状態とする操作装置を設け、旋回時の走行が停滞することのない作業車両を提供する。【解決手段】走行装置11,11と伝動切替装置300を走行斜体2に左右一対設け、走行車体2を左右方向に旋回操作する操作部材34を設け、操作部材34の操作に連動して旋回内側の伝動切替装置300を「切」側に作動させる旋回連動機構307を設け、旋回連動機構307と切替部材305を連結する連動操作機構317を設け、伝動操作部材303を設け、伝動操作部材303と切替部材305を連繋操作部材304で連結して構成する。【選択図】 図3
