PROBLEM TO BE SOLVED: To provide a combustion device capable of preventing exhaust gas from butting to an adjacent wall, etc.SOLUTION: An oblong exhaust pipe 17 is provided on the front surface of an appliance case 40, and the exhaust gas is exhausted via the exhaust pipe 17 from an outlet port 18 provided on the side surface of the exhaust pipe. The outlet port 18 is provided with a louver 19 for regulating the flow direction of the exhaust gas. The louver 19 is formed by aligning/arranging a plurality of blades 21 obliquely to be spaced from each other in the longitudinal direction of the appliance case 40. On a rear side surface and a front side surface on the front and the back of each blade 21, the rear side surface is made to be a laminar flow forming surface 32, and the front side surface is made to be a guide surface 33 of the exhaust gas. The guide surface 33 is formed with a tapered surface 22 which projects so that a projection amount to the front side can be larger toward the end side on the downstream side of the exhaust gas flow. The tapered surface 22 is made to be a forcible guide surface which forcibly guides a feeding direction of the exhaust gas to a predetermined direction on the diagonally front side. |
