Abstract: In an automotive vehicle in which an air duct which forms an air guide passage for guiding air that has flowed into an engine compartment to an induction system of an internal combustion engine is provided integrally on an inner surface of a bonnet, a reduction in size and weight of the air duct and a compact disposition of the air duct within the engine compartment are attempted to be realized. An automotive vehicle includes an internal combustion engine 20 which is disposed within an engine compartment and an air duct 40 which is provided integrally on an inner surface of a bonnet 10. The air duct 40 forms an air guide passage 60 for guiding air that has flowed into the engine compartment to an induction system 20i of the internal combustion engine 20 between itself and a bonnet portion 30 which constitutes part of the bonnet 10 in cooperation with the bonnet portion 30.

Abstract: An air cleaner device that has a reduced size achieved by curving an air introduction path, that has a cleaner element with extended service life, and in which air flows uniformly in a clean chamber. The air introduction path (21) having an exit (21o) open to a dust chamber (12) of an air cleaner chamber (11) of an air cleaner (10) has a bent path partitioned by a flow regulation plate (22) into an inside branch path (23) inside the curve and an outside branch path (24) outside the curve. Airflows separately flowing into the dust chamber (12) from the exit (21o) after passing through the inside and outside branch paths (23, 24) are deflected upward and directed toward the cleaner element (F) by a first deflection section (33) and a second deflection section (34) arranged in the dust chamber (12). The second deflection section (34) is located at a position closer in the front-rear direction to the exit (21o) than the first deflection section (33).
