PROBLEM TO BE SOLVED: To provide an exhaust gas after-treatment device capable of effectively protecting an NOx controller from heat and water with a simple structure and in a limited space.SOLUTION: An exhaust gas after-treatment device includes, as a frame 30, a plate-like top board 31 supporting an NOx reduction device body 23, and a leg part connected to a bottom surface of the top board 31 and supporting the top board 31. An NOx controller 26 is attached to a side surface of a bracket body 41 extending toward the lower part of a bracket 40 for controller provided on the top board 31, and at least an upper surface of the NOx controller 26 is covered with the bracket 40 for controller or the top board 31.SELECTED DRAWING: Figure 1

    【課題】排気ガス後処理装置において、簡単な構成かつ限られたスペースで、NOxコントローラを熱と水から効果的に防護できるようにする。【解決手段】架台30として、NOx還元装置本体23を支持する板状の天板31と、天板31の底面に連結され、天板31を支える脚部とを設ける。NOxコントローラ26を、天板31に設けたコントローラ用ブラケット40の下方に延びるブラケット本体41における側面に取り付け、少なくともNOxコントローラ26の上面をコントローラ用ブラケット40又は天板31で覆う。【選択図】図1
