PROBLEM TO BE SOLVED: To provide a work vehicle suppressing as much as possible a protrusion of traveling operation members located at a front part of a frame of the traveling vehicle body from the frame and facilitating operability.SOLUTION: A work vehicle equipping in a traveling vehicle body 2 with a brake pedal 70 for operating in a state of being seated on a drivers seat 31, and a brake locking mechanism for locking the brake pedal 70 in a brake operating state, and a brake assisting member for operating the brake pedal 70 from the outside of the traveling vehicle body 2. The brake assisting member has a brake assisting member S1 on the side of a frame of the brake pedal 70, providing a brake locking switching mechanism for switching between a locked state and an unlocked state by operating an operating portion 82c of the brake assisting member S1 from the outside of the traveling vehicle body 2, configured such that the brake assisting member S1 does not protrude to the outside of the traveling vehicle body 2 even if it is operated in either the locked state or the unlocked state by rotation restricting members 82d, 85.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2018,JPO&INPIT【課題】走行車体の機体前部に位置する走行操作用の部材の機体からの突出をなるべく抑え、且つ操作性も容易である作業車両の提供である。【解決手段】走行車体2に、運転席31に着座した状態で操作するブレーキペダル70と、ブレーキペダル70をブレーキ作動状態にロックするブレーキロック機構と、走行車体2の外側からブレーキペダル70を操作するブレーキ補助部材を装着した作業車両において、ブレーキ補助部材は、ブレーキペダル70の機体側方にブレーキ補助部材S1有し、ブレーキ補助部材S1の操作部82cが走行車体2の外側から操作されることでロック状態とロック解除状態に切り替えるブレーキロック切替機構を備えており、且つブレーキ補助部材S1は回動規制部材82d,85によりロック及びロック解除状態のいずれの状態に操作しても走行車体2の外側に突出しない構成とする。【選択図】図5
