Therefore, power unit 102 is according to situations such as the ground-surface in travelling are concavo-convex, with respect to vehicle body frame 101 along up and down or the fore-and-aft direction swing.In the present embodiment, the amplitude of fluctuation that reaches fore-and-aft direction up and down of power unit 102 depends on the operating space of connecting rod mechanism 130 and the elastic performance of buffering unit 127.
In this embodiment, on driving engine 141, fuel injector is installed.Fuel injector is the device that the delivery volume of the fuel that supplies to driving engine 141 is controlled, and has fuel injection valve 145.As shown in Figure 1 and Figure 2, fuel feed pipe 104 is equipped between the connecting portion 102a of Fuel Tank 103 and power unit 102 sides.In this embodiment, the fuel injection valve 145 of the fuel injector on fuel feed pipe 104 and the driving engine 141 that is installed in power unit 102 is connected.The connecting portion 102a of power unit 102 sides of this fuel feed pipe 104, runout moves when power unit 102 swings, and swings relatively with respect to vehicle body frame 101.The operation area (wobble area) of connecting portion 102a of representing power unit 102 sides of above-mentioned fuel feed pipe 104 by the dotted line A among Fig. 1.
In the present embodiment, fuel feed pipe 104 comprises fixed part 151, first extension 152, second extension 153 and curve 154.Fig. 2 is the birds-eye view of vehicle body frame 101, among Fig. 2, and 103 expression Fuel Tanks; 104 expression fuel feed pipes; 145 expression fuel injection valves.In this embodiment, the connecting portion 102a of power unit 102 sides of fuel feed pipe 104 is connected with fuel injection valve 145.And in this embodiment, Fuel Tank 103 is equipped on the rear of fuel injection valve 145.Specifically, Fuel Tank 103 is equipped on the rear side in the storage box 124 of the rear portion of vehicle under the seat 125 that sets on the power unit 102.
Fixed part 151 is the parts that are fixed on the vehicle body frame 101.In this embodiment, fuel feed pipe 104 is from Fuel Tank 103 along vehicle body frame 101 and extend.As shown in Figure 2, fixed part 151 with the stationkeeping at the connecting portion deflection rear of power unit 102 sides of comparing fuel feed pipe 104 on vehicle body frame 101.Specifically, in this embodiment, fixed part 151 is located at the middle part of fuel feed pipe 104, is fixed by the secure component 160 that is installed on the vehicle body frame 101.And the connecting portion 102a that fixed part 151 is compared power unit 102 sides departs from backward.And in this embodiment, fixed part 151 is to fix to the position (position of departing to the left in this embodiment) that the Width of car body departs from respect to the connecting portion 102a of power unit 102 sides.In this embodiment, fixed part 151 is fixed on the back stay 114 in vehicle body frame 101 left sides.
In this embodiment, fixed part 151 is fixed on the position that the connecting portion 102a with respect to power unit 102 sides departs to the left side of the Width of car body, and first extension 152 departs to the side (being the left side in this embodiment) of the Width of car body and sets.The curve 154 and first extension 152 are continuous and crooked.In this embodiment, the curve 154 and first extension 152 are continuously and to Width (the being right direction in this embodiment) bending of car body.And second extension 153 of fuel feed pipe 104 and curve 154 extend to the Width of car body continuously.In this embodiment, more particularly, first extension 152 extends from the fore-and-aft direction of fixed part 151 to car body.And curve 154 is from the Width bending of first extension 152 to car body, and second extension extends and is connected with the connecting portion 102a of power unit 102 sides to the Width of car body from curve 154.
In this embodiment, as shown in Figure 3 and Figure 4, fuel feed pipe 104 is made of forming tube.That is, in this embodiment, the fuel feed pipe 104 of the rubber system between Fuel Tank 103 and connecting portion 102a is shaped with aforesaid predetermined shape.And as depicted in figs. 1 and 2, the part between the connecting portion 102a of fixed part 151 and power unit 102 sides is mainly carried out elastic deformation according to the swing with respect to the power unit 102 of vehicle body frame 101.And, in this embodiment, set the amount of bow of curve 154, taking the occupant under the state of scooter-type vehicle 100, first extension 152 and second extension 153 set with the right angle.Thus, fuel feed pipe 104 is a benchmark with the state that the occupant takes, and follows the swing of power unit 102 and elastic deformation.The distortion of fuel feed pipe 104 that therefore, can be when travelling suppresses for less.In this embodiment, the state of taking with the occupant is as benchmark, the height of the connecting portion 102a of power unit 102 sides of the fixed part 151 of fuel feed pipe 104 and fuel feed pipe 104 roughly becomes equal height, and first extension 152, second extension, 153 approximate horizontal ground extend.
According to described scooter-type vehicle 100, though fuel feed pipe 104 at power unit 102 with respect to vehicle body frame 101 relatively under the situations of swing, Fuel Tank 103 is to the also runout action hardly of position of fixed part 151.Therefore, integral body can not vibrated tempestuously yet.
For example, in this embodiment, as shown in Figure 2, specific rigidity is higher mutually with other parts at the position (curve 154) of the bending between first extension 152 and second extension 153.And first extension 152 of fuel feed pipe 104 extends along the fore-and-aft direction of car body, and second extension 153 is along the Width extension of car body.In this embodiment, at power unit 102 with respect to vehicle body frame 101 along under the situation of knee-action, the runout action along the vertical direction of main first extension 152 that extends along the fore-and-aft direction of car body, or first extension 152 reverse, fuel feed pipe 104 is followed the action of power unit 102 thus.On the other hand, under the situation that power unit 102 moves along front and back with respect to vehicle body frame 101, main second extension 153 that extends along the Width of car body moves along the fore-and-aft direction runout, or the amount of bow of first extension 152 and second extension 153 changes, and fuel feed pipe 104 is followed the action of power unit 102 thus.Therefore, the space that sets fuel feed pipe 104 about between the connecting portion 102a of the fixed part 151 of fuel feed pipe 104 and power unit 102 sides needn't be provided with too big zone.
In this embodiment, the fore-and-aft direction of first extension 152 from fixed part 151 along car body extends, to extending to the position that the Width of car body departs from respect to the central portion of the operating space A of the connecting portion 102a of above-mentioned power unit 102 sides.And, the Width bending of curve 154 from first extension 152 along car body, second extension 153 extends and is connected with the connecting portion 102a of power unit 102 sides to the Width of car body from curve 154.Therefore, the central portion of operating space A when power unit 102 swing, is positioned at the center in zone of connecting portion 102a action of power unit 102 sides of fuel feed pipe 104.First extension 152 is along extending to the position that the Width of car body departs from respect to the central portion of this operating space A.In this case, for example power unit 102 is when fore-and-aft direction is swung, and the end that is connected of second extension 153 that is connected with the connecting portion 102a of power unit 102 sides of fuel feed pipe 104 is stretched along fore-and-aft direction.At this moment, first extension 152 moves hardly.That is, because second extension 153 that broad ways is extended direction runout action forwards, backwards, fuel feed pipe 104 can be followed the action of the connecting portion 102a of power unit 102 sides.Thus, in this embodiment, follow the action of power unit 102, the deflection integral body during fuel feed pipe 104 distortion is not too large.Therefore, the space that sets fuel feed pipe 104 between the connecting portion 102a of the fixed part 151 of fuel feed pipe 104 and power unit 102 sides also can be littler.In addition, as mentioned above, when power unit 102 swing, as long as can obtain making the little effect of quantitative change of first extension, 152 actions, " with respect to the central portion of operating space A to position that the Width of car body departs from " comprises near the position of this position and this position.
In addition, in this embodiment, first extension 152 extends from the fore-and-aft direction of fixed part 151 to car body, but needn't also can tilt a little with respect to the fore-and-aft direction of car body strictly to the fore-and-aft direction extension of car body.And, second extension 153 is from the Width bending of first extension 152 to car body, extends and is connected with the connecting portion of power unit 102 sides to the Width of car body, in this case, strictly speaking, also can tilt a little from the Width of car body.For example, first extension 152 can tilt with respect to the fore-and-aft direction of car body about 15 degree.And second extension 153 also can tilt with respect to the Width of car body about 15 degree.Promptly, even first extension 152 tilts about 15 degree with respect to the fore-and-aft direction of car body, and second extension 153 tilts about 15 degree with respect to the Width of car body, also can be as described above, follow the action of power unit 102 and make the fuel feed pipe distortion.And, at this moment, the runout action hardly of 151 the position from Fuel Tank 103 to fixed part of fuel feed pipe 104, integral body can not vibrated significantly yet.
And in this embodiment, fixed part 151 is fixed on the position that a side from the Width of car body (being the left side in this embodiment) departs from.One side (being the left side in this embodiment) of the Width of first extension, 152 deflection car bodies sets.The direction of the runout action of above-mentioned first extension 152 does not limit, and the amount of runout action can be suppressed for less.For example, in this embodiment, the lower-left side of storage box 124 bottoms of first extension 152 under the seat 125 and setting.Because the direction of the runout of above-mentioned first extension 152 action does not limit, the amount of runout action can be suppressed for less, thereby can form chamfering by the lower-left side that makes storage box 124 bottoms under the seat 125, form the space that sets this first extension 152.Thus, this scooter-type vehicle 100, under the situation of power unit 102 with respect to vehicle body frame 101 runouts actions, thereupon, fuel feed pipe 104 reasonably is out of shape, thereby the space that sets fuel feed pipe 104 also needn't be provided with too big zone.On the other hand, in this embodiment,, the amount of runout action can be suppressed for less, thereby can increase the capacity of storage box 124 because the direction of the runout action of first extension 152 that sets along the lower-left side of storage box 124 bottoms does not limit.So, can be limitedly the deflection of fuel feed pipe 104 be suppressed for less, thereby can dwindle the space that sets of fuel feed pipe 104, thereby strengthen the degree of freedom that sets space, equipping position etc. of miscellaneous part.
In this scooter-type vehicle 100, adopt fuel injector as described above, owing to omit graphic pump the fuel in fuel feed pipe 104 circulations is applied with sizable pressure.Therefore, use pipe arrangement at fuel feed pipe 104 with the desirable wall thickness that can hold out against above-mentioned fuel flow pressure.Therefore, in the situation that adopts fuel injector etc., fuel feed pipe 104 adopts rigidity higher, the fuel feed pipe that flexibility is relatively poor.In this embodiment, because as mentioned above, fuel feed pipe 104 reasonably be out of shape, thereby column plate type vehicle 100 preferably uses rigidity higher, the fuel feed pipe that flexibility is relatively poor.
And in this embodiment, as shown in Figure 2, fuel feed pipe 104 is along the back stay in the left side of scooter-type vehicle 100 and set.On the other hand, electric systems such as exhaust muffler 201 (noise silencer), electrical generator 202 are equipped on the right side of scooter-type vehicle 100.Thus, electric systems such as exhaust muffler 201 (noise silencer), electrical generator 202 are separated with fuel feed pipe 104.Thus, in this embodiment, thermal source, electric system are arranged, set fuel feed pipe 104 at its opposite side, thereby thermal source, electric system are separated with fuel feed pipe 104 owing to concentrating in a side of scooter-type vehicle 100.Thus, can prevent to exert an influence through the fuel of fuel feed pipe, thereby obtain suitable fuel feeding by the heat convection that described device produces.
