Abstract

An external air introduction apparatus includes: an external air introduction opening that guides external air into an exhaust channel, and opened and closed by a pressure difference between an external air pressure and a pressure inside the exhaust channel; a valve plate having a valve body that elastically deforms due to the pressure difference; a base plate stacked on the valve plate and having an opening that faces the valve body and smaller than the valve body and a seat surface formed around the opening; and a restriction plate that restricts elastic deformation of the valve body. The opening is closed and opened by the contact and separation of the valve body and the seat surface. The plates are fixed to a wall that forms the exhaust channel with a fastening member.
