An exhaust tube includes one end portion and the other end portion and is connected at one end portion to a combustion apparatus, of which inside is defined as an exhaust passage for combustion gas. An exhaust pipe has an outer diameter greater than that of exhaust tube, into which a part of exhaust tube on a side of the other end portion is introduced. An exhaust adapter is attached between an outer circumferential surface of exhaust tube and an inner circumferential surface of exhaust pipe. On the side close to the other end portion in exhaust tube relative to exhaust adapter, an exhaust passage holeis provided separately from an opening in the other end portion of exhaust tube. Exhaust passage hole has an opening area greater than a cross-sectional area of the exhaust passage and is in communication with the exhaust passage.
