摘要：An air flow sensor includes a duct forming a part of an intake passage, and adetection device. A swirl generating structure is also arranged in the duct to generate aswirl in the duct. A projection extending upstream from the opening at the upstream endof the duct is further disposed on the swirl generating means. Thus, the air flow rate canbe accurately detected without requiring a structural member for the intake system.
