It is an object of the present invention to provide an engine device in which a support structure of an exhaust throttle device can be made as a high rigidity structure, and it is possible to prevent the exhaust throttle device from being heated by radiation heat from peripheries of the exhaust throttle device. The engine device of the invention includes an engine (1) having an exhaust manifold (7), and the exhaust throttle device (65) adjusts exhaust gas pressure of the exhaust manifold (7). An exhaust gas intake side of a throttle valve case (68) of the exhaust throttle device (65) is fastened to an exhaust gas outlet of the exhaust manifold (7), and an exhaust gas pipe (72) is connected to the exhaust manifold (7) through the throttle valve case (68). An intermediate portion of a cooling pipe of an EGR cooler (29) is provided with a cooling water pipe of the exhaust throttle device (65). |
