PROBLEM TO BE SOLVED: To provide an intake noise suppressor capable of improving sound-deadening performance for suppressing the intake noise of an engine without restrictions on the layout and design around an intake system and a saddle riding type vehicle including the same.SOLUTION: A noise suppressor 200 includes an air cleaner 5, an intake funnel 6, and a resonator 7, and is connected to an engine 3 via a throttle body 4. The resonator 7 is provided within the air cleaner 5. The resonator 7 includes a chamber portion 110 and a pipe portion 120. The pipe portion 120 is formed to extend downward from the chamber portion 110 and includes an opening end 121 in a lower end portion. The intake funnel 6 is provided on a lower end of the air cleaner 5. An open end 121 of the resonator 7 is inserted into the intake funnel 6. A cross-sectional area of an intake passage between the intake funnel 6 and the pipe portion 120 is set equal to or larger than an opening area of an intake passage of the throttle body 4 at a maximum throttle opening.

    【課題】吸気系統周辺のレイアウトおよびデザインを制限することなくエンジンの吸気音の消音性を向上させることが可能な吸気消音装置およびそれを備える鞍乗型車両を提供する。【解決手段】吸気消音装置200は、エアクリーナ5、吸気ファンネル6およびレゾネータ7を含み、スロットルボディ4を介してエンジン3に接続される。エアクリーナ5の内部にレゾネータ7が設けられる。レゾネータ7は、チャンバ部110および管部120を含む。管部120はチャンバ部110から下方に延びるように形成され、下端部に開口端121を有する。エアクリーナ5の下端に吸気ファンネル6が設けられる。レゾネータ7の開口端121が吸気ファンネル6内に挿入される。吸気ファンネル6と管部120との間の吸気通路の断面積は、最大スロットル開度におけるスロットルボディ4の吸気通路の開口面積以上に設定される。【選択図】図9
