とを特徴とする排気切換装置。 A housing with a passageway that branches exhaust gas from one direction into two on the downstream side and flows through it; and a housing that is housed in the housing and selectively switches exhaust gas from one direction to one of the two downstream passageways. The switching valve has a central portion rotatably supported by a shaft, and a front end located on the upstream side of the shaft with respect to the shaft, the switching valve having a tapered shape. The rear end located on the downstream side of the exhaust has a flared shape and seals the exhaust between the end face of the rear end and the housing, while the housing has a part where the front end stops at a predetermined switching position. An exhaust switching device characterized in that a stepped portion is formed in the exhaust switching device.
