Since the pair of left and right fixing portions 73 and the pair of left and right bosses 56 are disposed on the sides of the fuel intake valve 60, the side portions of the fuel intake valve 60 can be protected by the fixing portions 73 and the bosses 56 of the joint 70. Thereby, even if the fuel injection valve 60 is a vehicle that is not covered with a vehicle body cover or the like, sufficient protection of the fuel injection valve 60 can be ensured.

また、本実施形態の鞍乗り型車両の吸気構造によれば、左右一対のボス５６は、燃料噴射弁６０の両側方に形成され、ジョイント７０の左右一対の固定部７３は、二股に分岐すると共に燃料噴射弁６０の両側方に延出し、左右一対のボス５６に取り付けられるため、燃料吸気弁６０の両側方をジョイント７０の左右一対の固定部７３と左右一対のボス５６で保護することができ、また、ジョイント７０の左右一対のボス５６への固定を良好にすることができる。   Further, according to the intake structure of the saddle-ride type vehicle of this embodiment, the pair of left and right bosses 56 are formed on both sides of the fuel injection valve 60, and the pair of left and right fixing portions 73 of the joint 70 are bifurcated. At the same time, the fuel injection valve 60 extends to both sides of the fuel injection valve 60 and is attached to the pair of left and right bosses 56. Therefore, both sides of the fuel intake valve 60 can be protected by the pair of left and right fixing portions 73 of the joint 70 and the pair of left and right bosses 56. Further, the joint 70 can be fixed to the pair of left and right bosses 56 favorably.

また、本実施形態の鞍乗り型車両の吸気構造によれば、吸気管５０は、吸気通路５４が車両前後方向に延設されると共に屈曲部５２を有し、燃料噴射弁６０及び左右一対のボス５６は、屈曲部５２において車幅方向に沿って並ぶように配置され、左右一対のボス５６には、左右一対の固定部７３とボルト８２により締結される雌ねじ５８が形成されるため、左右一対のボス５６の雌ねじ５８の長さを容易に確保することができ、ジョイント７０の左右一対のボス５６への固定を更に良好にすることができる。   Further, according to the intake structure of the saddle-ride type vehicle of the present embodiment, the intake pipe 50 has the intake passage 54 extending in the vehicle front-rear direction and the bent portion 52, and the fuel injection valve 60 and the pair of left and right The bosses 56 are arranged in the bent portion 52 so as to be aligned along the vehicle width direction. Since the female screws 58 fastened by the pair of left and right fixing portions 73 and the bolts 82 are formed on the pair of left and right bosses 56, The length of the female screw 58 of the pair of bosses 56 can be easily secured, and the fixing of the joint 70 to the pair of left and right bosses 56 can be further improved.

また、本実施形態の鞍乗り型車両の吸気構造によれば、エンジン３０は、メインフレーム１２の下方に配置され、燃料噴射弁６０は、吸気管５０の上部に上下方向を指向して支持され、ジョイント７０は、燃料噴射弁６０の上方を覆い、燃料噴射弁６０への燃料供給路７２ａを有する接続管部７２がメインフレーム１２に沿って配置され、左右一対のボス５６は、燃料噴射弁６０と略平行に上下方向に延出され、左右一対の固定部７３は、左右一対のボス５６の上端に取り付けられ、左右一対のボス５６と略平行に上下方向に延出されるため、接続管部７２をメインフレーム１２で保護することができ、また、ジョイント７０を小型化することができる。   Further, according to the intake structure of the saddle-ride type vehicle of the present embodiment, the engine 30 is disposed below the main frame 12, and the fuel injection valve 60 is supported on the upper portion of the intake pipe 50 in the vertical direction. The joint 70 covers the upper side of the fuel injection valve 60, a connecting pipe portion 72 having a fuel supply path 72 a to the fuel injection valve 60 is disposed along the main frame 12, and the pair of left and right bosses 56 are formed of the fuel injection valve The pair of left and right fixing portions 73 are attached to the upper ends of the pair of left and right bosses 56 and extend in the up and down direction substantially parallel to the pair of left and right bosses 56. The portion 72 can be protected by the main frame 12, and the joint 70 can be reduced in size.

なお、本実施形態の変形例として、図６に示すように、ジョイント７０に、燃料噴射弁６０の前方に配置され、二股に分岐した左右一対の固定部７３間を連結する板状の前方保護部であるシールド板７４を形成するようにしてもよい。この場合、ジョイント７０の左右一対の固定部７３の強度を向上することができ、また、燃料噴射弁６０の前方がシールド板７４で覆われるので、燃料噴射弁６０の保護を更に確保することができる。   As a modification of the present embodiment, as shown in FIG. 6, a plate-like front protection that connects between a pair of left and right fixing portions 73 that are disposed in front of the fuel injection valve 60 and bifurcated into the joint 70, as shown in FIG. 6. You may make it form the shield board 74 which is a part. In this case, the strength of the pair of left and right fixing portions 73 of the joint 70 can be improved, and the front of the fuel injection valve 60 is covered with the shield plate 74, so that the protection of the fuel injection valve 60 can be further secured. it can.
