Abstract
A branch pipe is coupled to a middle portion of an outside-air connection pipe. A fresh-air inlet of the branch pipe opens into the outside air. A check valve is provided in the branch pipe. The check valve restrains air in the outside-air connection pipe from flowing out into the outside air via the branch pipe and allows the outside air to flow into the outside-air connection pipe via the branch pipe when an inside pressure of the outside-air connection pipe decreases to a specified negative pressure. The fresh-air inlet of the branch pipe is positioned at a specified level higher than a fresh-air inlet of the outside-air connection pipe and disposed in a space formed between wheel house panels and a mud guard.
