To allow for suppression of removal of airflow from piping at a position upstream of an air flowmeter.SOLUTION: An air cleaner 100 comprises: a casing 110 that accommodates a filter member 130; and an outlet pipe 120 that is provided in a downstream end of the casing 110, connected to an air inlet hose 200, and is smaller in a flow path cross sectional area than that of the casing 110. An air flowmeter 300 is provided in the outlet pipe 120. A throttle part 122 having a convex-shaped cross section and having a reduced inner diameter is formed from an upstream end 124 connected to the casing 110 to an installation position of the air flowmeter 300 in the outlet pipe 120.SELECTED DRAWING: Figure 2

    【課題】エアフローメータの上流における空気流の、配管からの剥離を抑制可能とする。【解決手段】エアクリーナ100は、フィルタ部材130を収容するケーシング110と、ケーシング110の下流端に設けられるとともにエアインレットホース200に接続されケーシング110よりも流路断面積の小さいアウトレットパイプ120とを備える。エアフローメータ300は、アウトレットパイプ120に設けられる。アウトレットパイプ120の、ケーシング110と接続される上流端124からエアフローメータ300の設置箇所に亘って、断面凸曲面状であり内径が縮小される絞り部122が形成される。【選択図】図2
