The swing type power unit includes an intake passage member above, and the link member is an upper link type disposed above the crankcase and includes a vehicle body side pivot shaft connected to the vehicle body frame side and the swing. In a fuel hose support structure for a saddle-ride type vehicle including a power unit side connecting shaft connected to the power unit side,

After the flexible portion 7c is bent, the flexible portion 7c is arranged between the connecting tube 63 and the link member 8 while curving (see also FIG. 2). It is connected to the injection valve 71.
The fuel hose 7 is supported on the way by a fuel hose support member 75 fixed to the intake passage member 6.
　燃料ホース支持部材75は、その一端側端部に形成され吸気管61に固定される固定部75ａと、他端側端部に形成され燃料ホース７を支持するホース支持部75ｂとを備える。
　固定部75ａは、吸気通路部材６のうちのスロットルボディ62側に固定されるようにしてもよいが、スロットルボディ62は機種共通部材のため、機種専用の支持部材取付け部を設けることが避けることが好ましい。
　一方、吸気管61は機種ごとに設計できる部材のため、機種専用の支持部材取付け部61ａを設けやすい。すなわち、本実施形態のように吸気管61側に固定部75ａを取付ける支持部材取付け部61ａを設けると機種共通性が向上する。 The fuel hose support member 75 includes a fixed portion 75a formed at one end portion thereof and fixed to the intake pipe 61, and a hose support portion 75b formed at the other end portion thereof and supporting the fuel hose 7.
The fixed portion 75a may be fixed to the throttle body 62 side of the intake passage member 6, but since the throttle body 62 is a member common to all models, avoid providing a support member mounting portion dedicated to each model. Is preferred.
On the other hand, since the intake pipe 61 is a member that can be designed for each model, it is easy to provide a support member mounting portion 61a dedicated to the model. That is, if the support member mounting portion 61a for mounting the fixing portion 75a is provided on the intake pipe 61 side as in the present embodiment, the commonality of models is improved.
　以上のような本実施形態の燃料ホース７の支持構造おいては、さらに図２に示されるように、スロットルボディ62は、車両前後方向位置において一部が車体側ピボット軸83の軸心Ｘに重なり、ホース支持部75ｂは、車両前後方向位置において一部がスロットルボディ62に重なっている。
　そのように、スロットルボディ62の少なくとも一部は車両前後方向位置において車体側ピボット軸83の軸心Ｘと重なり、ホース支持部75ｂの少なくとも一部が車両前後方向位置においてスロットルボディ62に重なるようにすれば、リンク部材８の揺動中心位置となる車体側ピボット軸83の軸心Ｘに対して近い位置でホース支持部75ｂが燃料ホース７を支持することとなる。
　したがって、スイング式パワーユニット３の前後の揺動が比較的大きくなりやすい上リンク式においても、燃料ホース７の特に前後の揺動量が効果的に抑えられ、燃料ホース７長さの短縮化や車両スペースの効率的利用が図られ、周辺レイアウトのクリアランス自由度が向上する。 In the support structure of the fuel hose 7 of the present embodiment as described above, as shown in FIG. 2, the throttle body 62 is partially located at the axial center X of the vehicle body side pivot shaft 83 in the vehicle front-rear direction position. The hose support portion 75b partially overlaps the throttle body 62 at the vehicle front-rear position.
As described above, at least a part of the throttle body 62 overlaps the axis X of the vehicle body side pivot shaft 83 at the vehicle front-rear position, and at least a part of the hose support portion 75b overlaps the throttle body 62 at the vehicle front-rear position. Then, the hose support portion 75b supports the fuel hose 7 at a position close to the axis X of the vehicle body side pivot shaft 83, which is the swing center position of the link member 8.
Therefore, even in the upper link type in which the swinging movement of the swing type power unit 3 tends to be relatively large, the swinging amount of the fuel hose 7 particularly in the front and rear is effectively suppressed, and the length of the fuel hose 7 is shortened and the vehicle space is reduced. Can be used efficiently, and the degree of freedom in clearance in the peripheral layout can be improved.
　また、図２に示されるように、車体側ピボット軸83の軸心Ｘとホース支持部75ｂとが、高さ方向位置において、スロットルボディ62に重なっている。
　そのように、車体側ピボット軸83の軸心Ｘとホース支持部75ｂを、車両前後方向位置のみならず高さ方向位置においても近付けることで、ホース支持部75ｂの揺動量がより少なくなっている。 Further, as shown in FIG. 2, the axial center X of the vehicle body side pivot shaft 83 and the hose supporting portion 75b overlap the throttle body 62 at the height position.
As described above, the axial center X of the vehicle body side pivot shaft 83 and the hose support portion 75b are brought close to each other not only in the vehicle front-rear direction position but also in the height direction position, so that the hose support portion 75b swings less. ..
　そして、図４に示されるように、燃料ホース支持部材75のホース支持部75ｂは固定部75ａよりも、車両前後方向位置において、車体側ピボット軸83の軸心Ｘ側に設けられている。
　そのように、ホース支持部75ｂが車体側ピボット軸83の軸心Ｘに近く配置されたことでホース支持部75ｂの揺動が低減している。 Then, as shown in FIG. 4, the hose support portion 75b of the fuel hose support member 75 is provided closer to the axial center X side of the vehicle body side pivot shaft 83 than the fixed portion 75a in the vehicle front-rear direction position.
As described above, the hose support portion 75b is arranged near the axis X of the vehicle body side pivot shaft 83, so that the swing of the hose support portion 75b is reduced.
　図５は、スロットルボディ62と吸気管61との接続部64の前後を左前方上側から見た斜視図であり、燃料ホース支持部材75の固定状態と、燃料ホース支持部材75による燃料ホース７の支持状態を示す。
　図示のように、固定部75ａを取付ける支持部材取付け部61ａが、スロットルボディ62に接合する吸気管61のフランジ部61ｂに隣接する位置に設けられている。
　剛性の高いフランジ部61ｂを活用して、それに隣接して支持部材取付け部61ａを設けたので、吸気管61において、支持部材取付け部61ａのための補強用の肉盛りの追加が不要となっている。 FIG. 5 is a perspective view of the front and rear of the connecting portion 64 between the throttle body 62 and the intake pipe 61 as viewed from the upper left front side. The fuel hose support member 75 is fixed and the fuel hose 7 is supported by the fuel hose support member 75. The support state is shown.
As shown in the figure, a support member attachment portion 61a for attaching the fixed portion 75a is provided at a position adjacent to the flange portion 61b of the intake pipe 61 joined to the throttle body 62.
Since the support member mounting portion 61a is provided adjacent to the highly rigid flange portion 61b, it is not necessary to add a reinforcement padding for the support member mounting portion 61a in the intake pipe 61. There is.
　また、本実施形態では、燃料タンク16が後輪17の上方に設けられているが、そのような配置上、燃料ホース７が長くなる自動二輪車１においても、燃料ホース７の揺動抑制の効果が好適に発揮され、好ましい燃料ホース７の支持構造となっている。 Further, although the fuel tank 16 is provided above the rear wheel 17 in the present embodiment, the effect of suppressing the swing of the fuel hose 7 is also provided in the motorcycle 1 in which the fuel hose 7 is long due to such an arrangement. Is favorably exhibited, and has a preferable fuel hose 7 support structure.
　一方、燃料噴射弁71が吸気管61の下流端、すなわち吸気通路部材６の下流端に配設されているが、そのような配置上、燃料ホース７が長くなる自動二輪車１において、この場合も燃料ホース７の揺動抑制の効果が好適に発揮され、好ましい燃料ホース７の支持構造となっている。 On the other hand, the fuel injection valve 71 is arranged at the downstream end of the intake pipe 61, that is, at the downstream end of the intake passage member 6, but due to such an arrangement, in the motorcycle 1 in which the fuel hose 7 becomes long, in this case as well. The effect of suppressing the swing of the fuel hose 7 is suitably exerted, and the structure for supporting the fuel hose 7 is preferable.
　また、図２、図４に示されるように、スロットルボディ62とエアクリーナ65との間を接続するコネクティングチューブ63とリンク部材８との間に、燃料ホース７のたわみ部７ｃが配置されている。そのため、燃料ホース７の配置において、コネクティングチューブ63とリンク部材８との間の空いたスペースが有効に活用されている。 Further, as shown in FIGS. 2 and 4, the flexible portion 7c of the fuel hose 7 is arranged between the linking member 8 and the connecting tube 63 that connects the throttle body 62 and the air cleaner 65. Therefore, in the arrangement of the fuel hose 7, the empty space between the connecting tube 63 and the link member 8 is effectively utilized.
