<p>PROBLEM TO BE SOLVED: To provide an exhaust gas control device that can easily shorten the length of a case in an exhaust gas moving direction although the exhaust gas control device can be constituted at low cost by decreasing the number of components of a casing structure provided with an intake pipe.SOLUTION: An exhaust gas control device 1 is provided with exhaust gas intakes 12 on outer peripheral surfaces of cases 5, 21, and 32, in which a diesel oxidation catalyst 2 and a diesel oxidation catalyst 3 are provided, on one end side and with exhaust gas outlets on outer peripheral surfaces of the cases 5, 21, and 3 on the other end side. Exhaust gas intake pipes 16 and exhaust gas outlet pipes 34 are provided at the exhaust gas intakes 12 and exhaust gas outlets respectively, and the exhaust gas intake pipes 16 and exhaust gas outlet pipes 34 are different in opening position in peripheral directions of the cases 5, 12, and 32.</p> |
