PROBLEM TO BE SOLVED: To provide a traveling vehicle capable of easily reducing manufacturing costs while it can prevent a reverse steering-wheel operation during backward traveling in which a steering operation direction during the backward traveling is opposite to a steering operation direction during forward traveling.SOLUTION: A traveling vehicle includes: a traveling machine body 1 which is supported by right and left traveling sections 2 a linear hydraulic transmission 53 which comprises a linear hydraulic pumps 55 and a linear hydraulic motor 56 a turning hydraulic transmission 54 which comprises a turning hydraulic pump 57 and a turning hydraulic motor 58 and a forced differential mechanism 61 which performs output of the linear hydraulic transmission 53 and output of the turning hydraulic transmission 54 by synthesizing them together. The traveling vehicle has a structure which is configured to make output of the turning hydraulic motor 58 changeable. An output control mechanism 58b of the turning hydraulic motor 58 is connected to an output control mechanism 55b of the linear hydraulic pumps 55, and the output of the turning hydraulic motor 58 can be switched to normal-rotation output or reverse-rotation output by a forward-traveling or backward-traveling operation of an operation tool 13 for traveling speed change.COPYRIGHT: (C)2013,JPO&INPIT【課題】前進時の操舵操作方向に対して後進時の操舵操作方向が逆になる後進時の逆ハンドル操作を防止できるものでありながら、製造コストを容易に低減できるようにした走行車両を提供しようとするものである。【解決手段】左右の走行部2にて支持される走行機体1と、直進油圧ポンプ55及び直進油圧モータ56を有する直進用油圧変速機53と、旋回油圧ポンプ57及び旋回油圧モータ58を有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の出力を合成して出力する強制デフ機構61を備える走行車両において、旋回油圧モータ58の出力を変更可能に構成する構造であって、直進油圧ポンプ55の出力制御機構55bに旋回油圧モータ58の出力制御機構58bを連結させ、走行変速用操作具13の前進操作または後進操作により、旋回油圧モータ58の出力を正転出力または逆転出力に切換え可能に構成したものである。【選択図】図6
