<p>PROBLEM TO BE SOLVED: To shorten the total length of a power generation device by providing it with an exhaust gas emission part for promoting the mixture of a ventilation flow and an exhaust gas flow and lowering the exhaust gas temperature while the engine is halted. SOLUTION: A casing structure for a power generation device comprises a casing for covering a power generation device totally, and a box 8 disposed inside an outer plate 1 so as to form a double structure with the plate 1 for covering an engine, a muffler, a generator and the like. The casing structure involves an opening 7 formed through one side of the plate 1, a rectangular framing ventilation outlet 8A formed through the box 8 onto the inner periphery of the opening 7 to emit a ventilation flow, and a rectangular framing exhaust gas outlet 9A on an exhaust pipe 9 situated within the inner periphery of the ventilation outlet 8A to emit an exhaust gas flow. That casing structure further comprises a rectangular framing guide member 21 with an inner periphery spreading radially outward toward the end, which guide member is fixed in the opening 7 with its outer periphery coupled onto the ventilation outlet 8A and encircling the end of the exhaust gas outlet 9A at an interval therebetween.</p> |
