摘要： An intake noise reduction device includes an air cleaner, an intake funnel and a resonator, and is connected to an engine via a throttle body. The resonator is provided inside of the air cleaner. The resonator includes a chamber portion and a pipe portion. The pipe portion is formed to extend downward from the chamber portion, and has an opening end at a lower end. The intake funnel is provided at a lower end of the air cleaner. An opening end of the resonator is inserted into the intake funnel. A cross sectional area of an intake passage between the intake funnel and the pipe portion is set to not less than an opening area of an intake passage of the throttle body opened to a maximum throttle opening.
