PROBLEM TO BE SOLVED: To provide a traveling vehicle capable of surely preventing runaway of a traveling machine body by a simple mechanism, and easily achieving the reduction of a manufacturing cost and the improvement of maintainability.SOLUTION: A traveling vehicle includes: a traveling machine body having left and right traveling parts 2 a hydraulic transmission 53 for direct advance, for driving the traveling parts 2 in the same direction a hydraulic transmission 54 for turning, for driving the traveling parts 2 in an opposite direction a differential mechanism 61 which combines the output of the hydraulic transmission 53 for the direct advance with the output of the hydraulic transmission 54 for turning and transmits them to the left and right traveling parts 2 a gear shifter 12 which controls the output of the hydraulic transmission 53 for the direct advance and a turning operator 10 which controls the output of the hydraulic transmission 54 for turning. In the traveling vehicle, a neutral support for maintaining the turning operator 10 at a direct advance position when the gear shifter 12 is supported at a neutral (output 0) position is provided, and when the gear shifter 12 is gear-shifted, the turning operator 10 can be operated to a left turning side or a right turning side.COPYRIGHT: (C)2013,JPO&INPIT【課題】走行機体の暴走防止を簡易な機構によって確実に行え、製造コストの低減やメンテナンス性の向上を容易に達成可能な走行車両を提供する。【解決手段】左右の走行部2を有する走行機体と、左右の走行部2を同一方向に駆動するための直進用油圧変速機53と、左右の走行部2を逆方向に駆動するための旋回用油圧変速機54と、直進用油圧変速機53の出力と旋回用油圧変速機54の出力を合成して左右の走行部2に伝達する差動機構61と、直進用油圧変速機53を出力制御する変速操作具12と、旋回用油圧変速機54を出力制御する旋回操作具10を備える走行車両において、変速操作具12が中立(出力0)位置に支持されているとき、旋回操作具10を直進位置に維持するための中立支持体を備え、変速操作具12が変速操作されたときに、旋回操作具10を左旋回側または右旋回側に操作可能に構成する。【選択図】図3
