Abstract
An exhaust pipe forming a flow path of exhaust gas of a vehicle includes a first end including a first opening, a first flange portion formed on the first end, and a cover member. The first flange portion is configured to be fastened to a second flange portion formed on a second end of another exhaust pipe. The cover member includes a held portion and an inner circumferential portion. The held portion is held between the first end and the second end when the first flange portion and the second flange portion are fastened together. The inner circumferential portion covers a region adjacent to the first opening in the inner circumferential surface of the exhaust pipe.
Claims18
An exhaust pipe forming a flow path of exhaust gas of a vehicle, the exhaust pipe comprising:
