摘要： A secondary air control valve connected to an exhaust system includes a passage forming member and a valve mechanism. The passage forming member includes a container unit and a plurality of fins. The container unit that defines therein an exit cavity and an exit passage. The plurality of fins projects from the container unit into the exit cavity such that the plurality of fins collides with counter-flow exhaust gas that counter-flows in a direction from the exit passage to the exit cavity through the first opening. The plurality of fins divides the exit cavity into a plurality of cavities, in which counter-flow exhaust gas forms a plurality of vortex flows.
