Air intake device of internal combustion enginge

摘要

An air intake device for use with an internal combustion engine (1) has an air cleaner case (21) adapted to be mounted on the engine to extend longitudinally along an upper wall of the engine. An opening (33) is formed in a longitudinal end portion of a bottom wall of the air cleaner case (21). An air cleaner body (22) has an open end (22b) that is connected to the opening (33) of the bottom wall of the air cleaner case (21) thereby to communicate an interior of the air cleaner body (22) with that of the air cleaner case (21). An air cleaner element (23) is put between the air cleaner body (22) and the air cleaner case (21) in a manner to extend across the opening (33) of the bottom wall of the air cleaner case (21).
