Abstract

PURPOSE:To prevent sticking of dust and scattering oils on a flow rate sensor without disturbance of air flow by providing the flow rate sensor having a Venturi part within a bend which changes the direction of flow of the air flowing out through the outlet of an air cleaner in the direction differing from the direction of flow of said air. CONSTITUTION:An air cleaner element 2 is mounted to an air cleaner 1 having an inlet 1A, and an outlet 1B is formed in the lower part thereof. A bend 8 is secured integrally to the outlet 1B, and a Venturi part 5 is formed in the inside of its horizontal part, and a detecting element 4 is mounted therein. A heat ray type mass flowmeter 3 is connected to the element 4. A flow rectifying member 6 is provided on the upper stream side of the part 5, and a netlike member 7 for preventing backfiers coming from an engine is provided on the down stream side. Thereby, the sticking of dust and scattering oils on the flow rate sensor is prevented without disturbance of air flow.
