To provide a work vehicle which enables reduction of a turning radius, can inhibit gravity center fluctuation caused by fuel consumption, inhibit occurrence of failure of a gas cylinder, and facilitate work of replacement of the gas cylinder.SOLUTION: A work vehicle has: a lower structure 2; an engine chamber which houses a gas engine 42 disposed at a rear part of a revolving super structure 4; a cabin 41 disposed at a left part in the revolving super structure 4 in a plan view; and a hydraulic oil tank chamber 471 which stores a hydraulic oil tank 46 disposed at a right part in the revolving super structure 4 in the plan view. The cabin 41 and the hydraulic oil tank chamber 471 are disposed at a spacing from each other in a lateral direction. A recessed part 47s opening forward and upward is formed between the cabin 41 and the hydraulic oil tank chamber 471. The recessed part 47s is provided with a cylinder storage box 61 having a door 60 through which the gas cylinder 6 that is a fuel supply source for the gas engine 42 can be taken in or out. A space SP1 is provided between the cylinder storage box 61 and a work machine 3.SELECTED DRAWING: Figure 3 【課題】旋回半径の低減、燃料消費のよる重心変動の抑制、ガスボンベの不具合発生の抑制、及び、ガスボンベの交換作業の容易化を実現可能な作業車両を提供する。【解決手段】作業車両は、下部走行体２と、上部旋回体４の後部に配置されるガスエンジン４２を収納するエンジン室と、平面視にて上部旋回体４における左部に配置されるキャビン４１と、平面視にて上部旋回体４における右部に配置される作動油タンク４６を収納する作動油タンク室４７１と、を有する。キャビン４１及び作動油タンク室４７１は、左右方向に離間して配置される。キャビン４１と作動油タンク室４７１の間には、前方及び上方に開く凹部４７ｓが形成される。凹部４７ｓには、ガスエンジン４２への燃料供給源であるガスボンベ６を出し入れ可能な扉６０を有するボンベ収容箱６１が設けられる。ボンベ収容箱６１と作業機３との間には、スペースＳＰ１が設けられる。【選択図】図３
