To provide a work vehicle which can prevent appearance from being deteriorated and manufacturing cost from increasing when providing a waste-heat hole on a bonnet etc so as to configure not to impart heat damage to a peripheral component by exhausting, from the waste-heat hole, heat generated by an exhaust gas post-processing device which and an engine are covered with the bonnet.SOLUTION: A work vehicle is configured to cover an exhaust gas post-processing device 16 provided above and in a rear-end approaching part of an engine, with a rear-end approaching part of the bonnet and a front-end approaching part of a spacer cover 37 in front of a heat-shield plate, and comprise the waste-heat holes 37c, 37d in a top plate part and a lateral plate of a spacer cover facing the exhaust gas post-processing device, so as to exhaust hot-air with high temperature raised by the exhaust gas post-processing device from waste-heat holes to outside the work vehicle.SELECTED DRAWING: Figure 7
【課題】ボンネットによってエンジンと共に覆う排気ガス後処理装置が発生する熱を、排熱孔から排気して周辺部品に熱害を及ぼさないように構成する場合に、この排熱孔をボンネット等に設ける際の外観の悪化や製作コストの悪化を防止することができる作業車両を提供する。【解決手段】エンジンの後部寄り上方に設ける排気ガス後処理装置16をボンネットの後部寄りと遮熱板より前方のスペーサーカバー37の前部寄りによって覆うと共に、この排気ガス後処理装置に臨むスペーサーカバーの天板部と側板部に排熱孔を設けて、当該排気ガス後処理装置によって高温となった熱気を排熱孔37c、37dから機外に排気するように構成する。【選択図】図7
