An engine-driven generator is provided that is formed by supporting an engine (3) and a generator (4) on a frame (2), wherein the frame (2) is formed as an open periphery framework type, within this frame (2) a duct member (31) is disposed around the outer periphery of the engine (3) and the generator (4), the duct member (31) defining a series of cooling air passages (32) between itself and the engine (3) and generator (4), a cooling fan (26) is provided in the cooling air passage (32), the cooling fan (26) being driven by the engine (3), an intake box (34) having an intake opening (38) at an outer end thereof and housing an electrical component (53, 55) is connected to the upstream end of the duct member (31), and an exhaust box (68) having an exhaust opening (73) at an outer end thereof and housing an exhaust muffler (74) of the engine (3) is connected to the other end of the duct member (31). A compact engine-driven generator that enables running noise to be reduced can thereby be provided.
An engine-driven generator formed by supporting on a frame an engine and a generator driven by the engine, wherein the frame is formed as an open periphery framework type frame, within the frame a duct member is disposed around an outer periphery of the engine and the generator, the duct member defining a series of cooling air passages between itself, the engine, and the generator, a cooling fan is provided in the cooling air passage, the cooling fan being driven by the engine to generate cooling air flowing from an upstream end side to a downstream end side of the duct member in the cooling air passage, an intake box having an intake opening at an outer end thereof and housing an electrical component is connected to the upstream end of the duct member, and an exhaust box having an exhaust opening at an outer end thereof and housing an exhaust muffler of the engine, said exhaust box being connected to the other end of the duct member, wherein the duct member and the intake box are connected by a seal that allows relative displacement therebetween.
