The invention provides an engine device which is configured so that a support structure for an exhaust gas throttle device (65) is highly rigid and so that exhaust gas pressure within the exhaust manifold (7) can be highly accurately adjusted. The engine device is provided with an engine (1) having the exhaust manifold (7) and adjusts exhaust gas pressure in the exhaust manifold (7) by the exhaust gas throttle device (65). The engine device is configured in such a manner that the exhaust gas inlet side of the throttle valve case (68) of the exhaust gas throttle device (65) is fastened to the exhaust gas outlet of the exhaust manifold (7), and that an exhaust pipe (72) is connected to the exhaust manifold (7) through the throttle valve case 68.
