も低減できる。The tubular member 13 is formed with a venturi having a narrowest portion at one place in the cylinder, and the sensor element 9 of the air flow meter and the sensor module 8 are formed in the narrowest portion.
It is inserted and fixed through. The sensor element 9 is
It is electrically connected to the control circuit 10 via a terminal pin or the like, and is connected to the engine control unit via an external connector 11. According to the above-mentioned configuration, since the body portion of the air flow meter is integrally formed in the body portion 2 of the air cleaner, space can be saved and the air flow meter body 7 and the air cleaner 1 can be fixed. It is possible to reduce the number of screw members and the like for mounting and also reduce the number of man-hours for mounting.
