To provide a traveling vehicle with an excellent energy saving property, capable of using a continuously variable transmission both for straight advance and revolving to reduce cost, and capable of reducing capacities of various kinds of devices for supplying hydraulic oil.SOLUTION: In a transmission 1 of a traveling vehicle comprising a common HST 11 for shifting and revolving, a revolving gear mechanism 18 has a first multi-disc clutch 93 and a second multi-disc clutch 96 that can freely switch rotation of a second element in a forward or reverse direction. The first and second multi-disc clutches 93, 96 disengage both the multi-disc clutches 93, 96 when an indicator is in a straight advance operation state with respect to a steering handle 170 of the vehicle; in a steering state, alternatively selects one of the multi-disc clutches 93, 96 as one to be engaged according to a steering direction; and interlocks the multi-disc clutches 93, 96 to increase a degree of engagement as an amount of steering increases.SELECTED DRAWING: Figure 1

    【課題】無段変速装置を直進用と旋回用とで共用とすることでコストを抑制することができ、作動油を供給する各種装置の容量を低減することができ省エネルギー性に優れた走行車を提供する。【解決手段】変速および旋回を行うための共通のHST11を備えた走行車のトランスミッション1において、旋回ギヤ機構18は、第2要素を正または逆方向に回転切替自在な第1多板クラッチ93と第2多板クラッチ96を有し、第1・第2多板クラッチ93・96は車両のステアリングハンドル170に対して、指示具が直進操作状態のときは両多板クラッチ93・96を非係合とし、操舵状態のときは操舵方向に応じて多板クラッチ93・96のいずれかを係合対象として択一選択し、操舵量が増えるにつれて多板クラッチ93・96の係合度を高めるように、連動連係させた。【選択図】図1
