延びる傾斜面に形成した吸入空気量検出装置。 A large bench lily is formed in the intake passage, and a small hollow cylindrical bench lily having a smaller diameter than the intake passage and extending in the axial direction of the intake passage is provided in the intake passage upstream of the large bench lily, and the outlet of the small bench lily is connected to the large bench lily. In the intake air detection device, the intake air detection device has a bypass passage connected to the small bench lily, which communicates the intake passage upstream of the small bench lily with the inside of the small bench lily, and a heat-sensitive resistance type flow velocity detection element is inserted into the bypass passage. An inlet passage section in which the bypass passage extends from the bypass passage inlet almost parallel to the axis of the small bench lily; and an outlet passage section in which the bypass passage extends along the outer periphery of the small bench lily toward the bypass passage outlet formed on the inner wall surface of the small bench lily. a bypass intake air guide wall extending diagonally downward from the outer inner wall surface of the inlet passage section to the bottom inner wall surface of the outlet passage section is formed at the connection part between the inlet passage section and the outlet passage section. In addition, the bottom wall surface of the bypass passage outlet is formed into an inclined surface extending diagonally downward toward the axis of the small bench lily.
