Abstract

See full text

An exhaust valve includes a pipe body connecting an upstream pipe and a downstream pipe for exhaust, a valve plate disposed inside the pipe body in a state of being attached to a rotary shaft that rotates by drive of an actuator, the valve plate configured to rotate to open/close an exhaust flow path inside the pipe body, and a stopper fixed inside the pipe body and configured to come into contact with the valve plate in a closed state. In the stopper, at least one of an upstream contact surface at which the valve plate makes contact and a downstream contact surface at which the valve plate makes contact runs along an inner peripheral surface of the pipe body at a position closer to an upstream side or a downstream side of the exhaust than an outer periphery of the rotary shaft.
