To provide an intake structure for an internal combustion engine for saddle-ride type vehicle in which damping performance of an intake pipe is improved and an injector or the like of a fuel injection device can be attached without trouble while preventing interference with damping means of the intake pipe.SOLUTION: In an intake structure for an internal combustion engine 4 for saddle-ride type vehicle in which an intake pipe 7 includes ribs 71, 72, 73 and 74 which are erected on both a left side face and a right side face and both an upper face and a lower face, an injector 81 is disposed between one of the left side face rib 73 and the right side face rib 74 and the upper face rib 71. In the intake structure for the internal combustion engine for saddle-ride type vehicle, with respect to vibration of a vehicle and vibration generated in the intake pipe, rigidity and a strength of the intake pipe are improved by the ribs on the left and right side faces and the upper and lower faces of the intake pipe, and damping performance is improved. Even in a case where the upper face rib 71 is formed, the injector can be disposed in the intake pipe while preventing interference with the ribs.SELECTED DRAWING: Figure 3

    【課題】吸気管の制振性が向上し、燃料噴射装置のインジェクタ等が吸気管の制振手段と干渉せず障害なく取付けられる鞍乗型車両用内燃機関の吸気構造を提供する。【解決手段】吸気管7に、左側面、右側面の両面、および上面、下面の両面にそれぞれ立設されたリブ71,72,73,74を備えた、鞍乗型車両用の内燃機関4の吸気構造において、左側面リブ73と右側面リブ74のうち一方側のリブと上面リブ71との間にインジェクタ81が配置され、車両の振動と吸気管に生じる振動に対して、吸気管の左、右側面、上、下面のリブによって吸気管の剛性と強度が高まり、制振性が向上するとともに、上面リブ71を形成した場合でも、各リブに干渉することなく、吸気管にインジェクタを配置することができる鞍乗型車両用内燃機関の吸気構造。【選択図】図3
