Abstract

PURPOSE:To elevate the extent of noise resistance, and also to make a device compact, by constituting an air cleaner body of an electric conductor so as to serve as a shielding case, too, and storing an air quantity measuring device in its inside. CONSTITUTION:An air cleaner body 1 is formed by an electric conductor, and in its inside, the whole suction air quantity measuring device 3 is stored together with a cleaner element 2, and a suction passage 5 is connected with an engine. An air quantity detecting part 6 in the air cleaner body 1 is constituted of a vortex generating post, an ultrasonic transmitter 61, a receiver 62, and conductors 63, 64, a measuring circuit 7 is stored in a case 8, and the case 8 is connected to the air cleaner body 1 by a connecting line 201. The flow velocity measuring ciruit 7 is fed from a battery 10, and its output is sent to an engine controller 11. Since the whole measuring device is stored in the air cleaner body serving as the shielding case, too, the extent of noise resistance is elevated, and also the device becomes compact.
