Abstract
An air flow meter disposed in an intake pipe has a bypass member having a U-shaped bypass passage, into which part of air flowing through the intake pipe is introduced. An outflow port disposed at a downstream air side of the bypass passage is surrounded at its three sides by opposing surfaces of a pair of side walls and a wall surface of a partition wall disposed at “an upstream air side of the outflow port”. Further, the outflow port is opened in an air flow direction in the bypass passage and in an air flow direction in the air flow passage. Therefore, air flowing through the bypass passage is partially discharged into the air flow passage through the outflow port gradually before joining main air flow in the air flow passage, thereby restricting decrease in air flow velocity and occurrence of turbulence in the bypass passage.
