<P>PROBLEM TO BE SOLVED: To provide an air flow measuring device 1 that measures air flow taken into an engine and that has a structure insusceptible to air pulsation or air deflection. <P>SOLUTION: In an air flow measuring device 1, a discharge port 8 opens toward a downstream side of an intake air path. Accordingly, even if air flowing in a forward direction in the intake air path is deflected, air discharge from the discharge port 8 is scarcely affected. Further, a path wall composing a discharge flow path 11 has a slit 17. When air flows in the reverse direction in the intake air path, part of the air from the discharge port 8 flows into an inner flow path 7, so that the air from the discharge port 8 goes back to the intake air path from the slit 17. Thus, effect of air pulsation on an output value of a sensor 2 can be reduced. Accordingly, a structure insusceptible to air pulsation or air deflection can be provided for the air flow measuring device 1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
