Abstract
An air flow measuring device includes an air flow meter (AFM), a straightening grid, and a mesh member. The AFM includes an air inlet and is configured to measure a flow rate of air flowing into the air inlet. The straightening grid includes a straightening plate having only one crossing region and is disposed on an upstream side of the AFM in a flow direction of air to straighten a flow of air toward the AFM through the straightening plate. The mesh member is formed in a netted manner and is disposed between the straightening plate and the AFM.
