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.

Abstract: A changeover valve includes: a valve body portion that closes an opening formed at a switching position of an exhaust flow path; a fixing portion that rotatably fixes the valve body portion; a first raised portion protruding at one of a flow path forming portion and the fixing portion; a cushion portion; a second raised portion protruding at the valve body portion; and a biasing portion that biases the valve body portion. The first raised portion has an inclined portion inclined relative to a valve closing direction and the second raised portion has an inclined portion inclined relative to the valve closing direction. Both of the inclined portions are contactable with each other at the time of valve closing.
