Provided in the present invention is a combine, wherein an oxidation catalyst and an SCR catalyst are integrated in a compact manner, in order to reduce the space in which the oxidation catalyst and the SCR catalyst are arranged. To this end, an oxidation catalyst (21) is installed in a posture that an exhaust gas circulation direction corresponds to a vertical direction. An SCR catalyst (22) is installed in a posture that the exhaust gas circulation direction corresponds to a back-and-forth direction. A first support member (52) is installed in a vertical direction to support the oxidation catalyst (21) at one side of the right and left sides of the oxidation catalyst (21). A rear portion of the first support member (52) is arranged at a location which is at the back from a front portion of the first support member (52), and is leaning to one side of the right and left sides. An opening unit (53) is formed at a lower portion of the first support member (52). A portion of one side of the right and left sides in a front portion of the SCR catalyst (22) is inserted into the opening unit (53). (과제) 산화 촉매와 SCR 촉매를 컴팩트하게 일체화하여 산화 촉매와 SCR 촉매의 배치하는 공간을 작게 할 수 있는 콤바인을 제공한다. (해결수단) 산화 촉매(21)를, 배기가스 유통 방향이 상하 방향을 따르는 자세로 설치하고, SCR 촉매(22)를, 배기가스 유통 방향이 전후 방향을 따르는 자세로 설치하고, 산화 촉매(21)의 좌우 일측에, 산화 촉매(21)를 지지하는 상하 방향의 제1지지 부재(52)를 설치하고, 제1지지 부재(52)의 뒷부를, 제1지지 부재(52)의 앞부보다 후방이며 좌우 일측으로 치우친 위치에 배치하고, 제1지지 부재(52)의 하부에 개구부(53)를 형성하고, SCR 촉매(22)의 앞부에 있어서의 좌우 일측의 부위를 개구부(53) 내에 침입시킨다.
