Exhaust pipe

An exhaust pipe that forms an exhaust flow channel, the exhaust pipe comprising:

• a first flow channel member that forms part of the exhaust flow channel;
• and
• a second flow channel member that is connected in series with the first flow channel member and forms part of the exhaust flow channel,
• a downstream-side end of the first flow channel member being inserted into an upstream-side end of the second flow channel member,
• a communication channel that communicates between an inside and an outside of the exhaust pipe being formed between an outer surface of an insertion part of the first flow channel member and an inner surface of an insertion-receiving part of the second flow channel member, wherein the insertion-receiving part is arranged to face higher than a horizontal direction, and
• a cover that covers an opening of the communication channel from the outside so as not to be exposed, wherein the first flow channel member and the cover are formed of a single component,
• wherein the downstream-side end of the first flow channel member includes an enlarged diameter part, a folded part obtained by folding back inward a leading end of the enlarged diameter part, and a thin pipe part obtained by folding back inward the folded part,
• wherein the thin pipe part is inserted into the upstream side end of the second flow channel member, the thin pipe part being formed to have a smaller outer diameter than an inner diameter of the insertion part so that a regular gap is formed between an outer circumferential surface of the thin pipe part and an inner circumferential surface of the insertion-receiving part as the communication flow channel, and
• wherein the folded part is formed to have a larger inner diameter than an outer diameter of the insertion-receiving part, the folded part being arranged to overlap with a leading end of the insertion-receiving part in an axial direction, thereby to function as the cover.
