PROBLEM TO BE SOLVED: To avoid interference between a fuel injection valve and an air cleaner even if the air cleaner receives an excessive load from the front side due to some kind of events in an internal combustion engine for saddle-riding type vehicle in which the air cleaner is arranged between a cylinder head of an engine body arranged on the lower side of a main frame inclined backwardly and downwardly from a head pipe and extending to the rear side with the cylinder axis leaned forwardly and the main frame, and the fuel injection valve is attached to the front side of an intake passage formation member forming a portion of an intake passage connecting the air cleaner and an intake port of the cylinder head.SOLUTION: A part 65a to be attached which is provided on the upper side of an air cleaner 54 is fastened to a main frame 14 with a fastening member 74 having an axis extending in the vehicle width direction, and a fuel injection valve 63 is arranged on the outer side with respect to a virtual rotation trajectory CT1 drawn by a lowest edge part 54aa of a portion where the fuel injection valve 63 is arranged in the vehicle width direction of a lower edge part 54a of the air cleaner 54 with the axis of the fastening member 74 as the center.SELECTED DRAWING: Figure 3

    【課題】ヘッドパイプから後下がりに傾斜して後方に延出するメインフレームの下方に配置されてシリンダ軸縁を前傾させた機関本体のシリンダヘッドと、メインフレームとの間にエアクリーナが配置され、エアクリーナとシリンダヘッドの吸気ポートとを結ぶ吸気通路の一部を形成する吸気通路形成部材の前側に燃料噴射弁が取付けられる鞍乗り型車両用内燃機関において、エアクリーナが何らかの事象によって前方から過大な荷重を受けても燃料噴射弁およびエアクリーナの干渉を回避する。【解決手段】エアクリーナ54の上部に設けられる被取付け部65aが、車幅方向に延びる軸線を有する締結部材74でメインフレーム14に締結され、エアクリーナ54の下縁部54aのうち車幅方向で前記燃料噴射弁63が配置される部分の最下縁部54aaが前記締結部材74の軸線を中心として描く仮想回転軌跡CT1よりも外方に、燃料噴射弁63が配置される。【選択図】 図3
