Abstract
An air cleaner has a body, an intake part to take air into the body, an exhaust pipe to exhaust the air from the body, a mounting section to mount an air flow meter to the exhaust pipe, a rib disposed on an inner surface of the body, and a straightening element disposed on an inner surface of the exhaust pipe. The rib extends toward the exhaust pipe and the straightening element extends in a same direction where the rib extends. The straightening element is located closer to the body than the mounting section.
