PROBLEM TO BE SOLVED: To provide a traveling vehicle capable of reducing a manufacturing cost and improving maintainability.SOLUTION: A traveling vehicle includes: a traveling machine body having left and right traveling parts 2 a hydraulic transmission 53 for direct advance, which drives the traveling parts 2 in the same direction a hydraulic transmission 54 for turning, which drives 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 traveling parts 2 a gear shifter 12 and a turning operator 10. In the traveling vehicle, a counter steering prevention means for making the steering direction of the turning operator 10 be matched with the turning direction of the traveling machine body is provided, the counter steering prevention means is disposed between a steering link mechanism connected to the turning operator 10 and a trunnion arm for turning, and the output of a hydraulic pump 57 for turning can be maintained at 0 regardless of the operation of the turning operator 10 by the neutral operation of the gear shifter 12.COPYRIGHT: (C)2013,JPO&INPIT【課題】製造コストを低減でき、メンテナンス性を向上できるようにした走行車両を提供しようとするものでる。【解決手段】左右の走行部2を有する走行機体と、行部2を同一方向に駆動する直進用油圧変速機53と、走行部2を逆方向に駆動する旋回用油圧変速機54と、直進用油圧変速機53の出力と旋回用油圧変速機54の出力を合成して走行部2に伝達する差動機構61と、変速操作具12と、旋回操作具10を備える走行車両において、旋回操作具10の操舵方向と走行機体の旋回方向を一致させる逆ハンドル防止手段を備え、旋回操作具10に連結する操向リンク機構と旋回用トラニオンアームとの間に逆ハンドル防止手段を配置し、変速操作具12の中立操作により旋回操作具10の操作に関係なく旋回用油圧ポンプ57の出力を0に維持可能に構成する。【選択図】図3
