To provide a technology that can suppress generation of deposit that is generated from a low-temperature exhaust gas by mixing the low-temperature exhaust gas with a high-temperature exhaust gas.SOLUTION: An exhaust system (10) includes: a heat exchanger (20) including a first pipe (50) for evacuating a low-temperature exhaust gas cooled by a cooling medium; a second pipe (60) for evacuating a high-temperature exhaust gas; and a merging part (40) including a merging space (70) where the low-temperature exhaust gas merges with the high-temperature exhaust gas. The merging space (70) is provided with: an obstruction part (80) for obstructing a flow of the low-temperature exhaust gas and a flow of the high-temperature exhaust gas; and a mixing space (71) for mixing the low-temperature exhaust gas and the high-temperature exhaust gas, which are stagnated by the obstruction part (80), with each other.SELECTED DRAWING: Figure 4 【課題】低温の排気ガスと高温の排気ガスを混ぜることにより、低温の排気ガスから生成される堆積物の生成を抑制できる技術を提供する。【解決手段】排気装置（１０）は、冷却媒体により冷却された低温排気ガスを排出する第１の管（５０）を、含む熱交換器（２０）と、高温排気ガスを排出する第２の管（６０）と、低温排気ガス及び高温排気ガスが合流する合流空間（７０）を含む合流部（４０）を有する。合流空間（７０）には、低温排気ガスの流れ及び高温排気ガスの流れを妨げる障害部（８０）と、この障害部（８０）によって滞留した低温排気ガス及び高温排気ガスが互いに混合する混合空間（７１）と、が設けられている。【選択図】図４
