PROBLEM TO BE SOLVED: To provide an exhaust gas aftertreatment unit capable of improving replenishing performance of cooling water in a reducing agent injection device, and a work vehicle.SOLUTION: An exhaust gas aftertreatment unit 20 includes a cooling water path 25 for guiding cooling water to a reducing agent injection device 24. The cooling water path 25 includes: a first flow passage F1 continuing to an inner flow passage 24a of the reducing agent injection device 24; and a second flow passage F2 and a third flow passage F3 that are branched from the first flow passage F1. A branch point FP at which the first flow passage F1 is branched into the second flow passage F2 and the third flow passage F3 is located above a connection portion between the reducing agent injection device 24 and the first flow passage F1. The third flow passage F3 extends from the branch point FP to an upper side of the second flow passage F2. The second flow passage F2 and the third flow passage F3 are merged with each other on the side opposite to the branch point FP.SELECTED DRAWING: Figure 7

    【課題】還元剤噴射装置への冷却水の補充性を改善することが可能な排気ガス後処理ユニット及び作業車両を提供する。【解決手段】排気ガス後処理ユニット20は、冷却水を還元剤噴射装置24に導く冷却水経路25を備える。冷却水経路25は、還元剤噴射装置24の内部流路24aに連なる第1流路F1と、第1流路F1から分岐する第2流路F2及び第3流路F3とを含む。第1流路F1が第2流路F2及び第3流路F3に分岐する分岐点FPは、還元剤噴射装置24と第1流路F1との接続部分よりも上方に位置する。第3流路F3は、分岐点FPから第2流路F2よりも上方に延びる。第2流路F2と第3流路F3は、分岐点FPの反対側において合流する。【選択図】図7
