FIG. 8 is a sectional view taken along the line 8-8 in FIG. 4, in which a recess 8a is formed in a part of the upper portion of the fuel tank 8, and the recess 8a is formed.
3A shows that at least a part of the reserve tank 9 is arranged. The fuel tank 8 has a fuel tank cap 75 attached to a fuel supply port 8b, and the reserve tank 9 has an inlet 9a.
Thus, the inlet cap 76 of the reserve tank 9 is disposed on the side of the fuel tank cap 75. Since the refueling port 8b and the filling port 9a are at a high position and are inclined obliquely rearward and downward, the refueling workability and the workability of injecting the coolant are good. The center cover 26 has a window 26a at an upper portion, and the window 26a is vertically divided by a partition plate 26b, and the oil supply port 8b and the injection port 9a are separated from the partition plate 26b by the window portion 26a.
And the window 26a is covered with a refueling lid 43.

As will be described later, the fuel tank cap 75
The inlet cap 76 is covered with one refueling lid 43. When one refueling lid 43 is opened, the fuel tank cap 75 and the inlet cap 76 are arranged. For this reason, by opening one refueling lid 43, the work of checking the fuel and the coolant and the work of replenishing can be performed, so that the workability is good. The number of refueling lids 43 can be reduced. Further, since a portion of the fuel tank 8 having a high degree of freedom in shape is recessed and at least a portion of the reserve tank 9 is disposed in the recess 8a, a space for disposing the fuel tank 8 and the reserve tank 9 can be reduced. , Space efficient. As will be described later, the cooling air passages 84, 84 are formed by cooling air Fc provided along the left and right step floors 23, 23.
It is a passage through which.

FIG. 9 is a sectional view taken along line 9-9 of FIG. 5, and shows that the step floors 23 are located on the left and right. The cooling air passages 84, 84 are provided along the left and right step floors 23, 23.
The left and right floor skirts 24, 24 are extended downward from the outer edge of No. 3, and the lower edges of the floor skirts 24, 24 are covered with an undercover 25. Therefore, since the step floors 23, 23, the floor skirts 24, 24 and the under cover 25 also serve as the cooling air passages 84, 84, there is no need to provide the cooling air passages 84, 84 made of separate members. For this reason, since the cooling air passages 84, 84 can be widened, the cooling air can flow efficiently, and the cooling efficiency of the radiator 10 can be increased. Also,
Since the cooling air passages 84, 84 made of separate members are unnecessary, the cooling air passages 84, 84 can have a simple structure and the number of parts can be reduced. Furthermore, center cover 2
Since the radiator 10 is disposed by effectively utilizing the space in 6, the radiator 10 can be set to a large height dimension. The radiator 10 has left and right lower parts attached to brackets 62d, 62d of the down tubes 62, 62, and an upper left part attached to a bracket 65a of the joint 65. Also, the left and right guide plates 85, 85
The lower part of the bracket 66d, 66 of the stay 66, 66
d, and the upper portion is clipped to brackets 65a, 65b of the joint 65.

Next, the flow of cooling air around the radiator 10 will be described with reference to FIG. FIG. 10 is an operation diagram around a radiator according to the present invention. The fan 81 behind the radiator 10 sucks wind from the front of the radiator 10. For this reason, the outside air becomes the cooling wind (including the running wind at the time of running the vehicle) Fc, enters the radiator air introduction ports 31b, 31b, flows through the cooling air passages 84, 84, and the guide plates 85, 8
The radiator 10 enters the radiator 10 by being guided. The hot air (discharged hot air) Fh that has passed through the radiator 10 is discharged from the fan 81 and changes its flow in the left-right direction and downward by the deflecting plate 82, and is discharged to the floor skirts 24, 24 and the under cover 25. , 25a to the outside. Hot air F flowing out of outlets 24a, 24a, 25a
h flows backward along the body cover 17 as it is.

As described above, the cooling air Fc flowing through the cooling air passages 84, 84 is guided by the guide plates 85, 85 to the radiator 10.
Therefore, the cooling air Fc can efficiently flow through the radiator 10. Therefore, the cooling efficiency of the radiator 10 increases. Further, since the direction of the hot air Fh passing through the radiator 10 is changed by the deflection plate 82, the influence of the hot air Fh on the water-cooled engine 11 behind the radiator 10 can be prevented.

Further, the hot air (wind) Fh whose direction is changed by the deflecting plate 82 is discharged to at least one of the floor skirts 24, 24 and the under cover 25, and the outlets 24a, 2 are opened.
Since the discharge is made more positively to the outside from 4a and 25a, the pressure loss on the discharge side is reduced. As a result, the cooling air Fc can efficiently flow through the cooling air passages 84, 84. Therefore, the cooling efficiency of the radiator 10 increases.

Further, since the rectifying mechanism 83 for regulating the flow of the wind is provided behind the radiator 10, the pressure loss on the discharge side is reduced. As a result, the cooling air Fc can efficiently flow through the cooling air passages 84, 84. Accordingly, even if vehicle equipment such as the fuel tank 8, the coolant reserve tank 9, and the fuel pump 74 is disposed in the cooling air passages 84 and 84 and in front of the radiator 10, an amount sufficient to cool the radiator 10 is provided. Can efficiently flow the cooling air Fc.
Therefore, the space of the cooling air passages 84, 84 can be effectively used.

The radiator air vents 31b are deviated to both sides with respect to the radiator 10 at the center of the vehicle width. For this reason, the radiator air vents 31b, 31
b, a restricting member (for example, a louver) for preventing muddy water entering from the radiator 10 from entering the radiator 10.
It is not necessary to provide the cooling air passages 84 and 84 immediately before.

Next, the left windshield 50 will be described with reference to FIGS. Note that the right windshield device 50 is symmetrical and has the same configuration as the left windshield device 50, and a description thereof will be omitted. FIG. 11 is a cross-sectional view taken along line 11-11 of FIG. 7, and shows the left air guide port 21a and the leg shield 22a. The leg shields 22a extend in the vehicle width direction from both sides of the inner cover 22, and a discharge port 22b opened at a side end thereof is directed obliquely rearward in the vehicle width direction. Wind guide 21a
Is a substantially cone-shaped through-hole whose diameter decreases toward the rear, and a duct 51 communicating with this through-hole is a substantially L-shaped duct whose outlet 51b is directed toward the outlet 22b of the leg shield 22a. . Since the duct 51 is L-shaped, the rear of the front cover 21 cannot be seen from the front of the scooter 1. For this reason, the appearance of the scooter 1 is enhanced. The outlet 51b of the duct 51 is separated from the outlet 22b of the leg shield 22a by a certain distance.

FIG. 12 is a sectional view taken along line 12-12 of FIG. 7, and shows that the lower portion of the left duct 51 is bolted to the inside of the front cover 21 via the stay 52 at one place.

FIG. 13 is a sectional view taken along line 13-13 of FIG.
2 shows that the upper portion of the left duct 51 has been bolted at two places. Thus, as is clear from FIGS. 11 to 13, the duct 51 is attached to the front cover 21,
Since the outlet 51b of the duct 51 is separated from the outlet 22b of the leg shield 22a by a certain distance, it is only necessary to attach the duct 51 to the front cover 21 only with three bolts. For this reason, the mounting structure of the duct 51 is simple, and the mounting operation is also easy.

FIGS. 14 (a) to 14 (e) are diagrams showing the configuration of the left duct according to the present invention, wherein FIG. 14 (a) is a side view, FIG. 14 (b) is a right side view of FIG. 14 (a), and FIG. FIG. 3D is a sectional view taken along line dd of FIG. 3A, and FIG. 3E is a sectional view taken along line ee of FIG. The left duct 51 has a size corresponding to the size of the inlet 51a corresponding to the wind guide port 21a and the size of the outlet 51b corresponding to the leg shield 22a.
2 and has a size that covers the plurality of outlets 22b.
Are guided almost equally to all the outlets 22b. The duct 51 has a drain hole 51c which is vertically penetrated in the lower part. For this reason, during rainy weather traveling, the rainwater that has entered through the wind guide port 21 a of the front cover 21 drains out from the drain hole 51 c opened in the lower part of the duct 51. For this reason, there is no concern that water will collect on the bottom of the front cover or the bottom of the duct.

Next, the left and right windshields 50, 5 of the above construction
The operation of 0 will be described with reference to FIG. FIG. 15 is an operation diagram of the windshield device according to the present invention. While traveling on scooter 1,
Running wind (frontal flow) F toward the front of the front cover 21
A part of w enters the air introduction port 21a, passes through the duct 51,
The gas flows out obliquely rearward from a discharge port 22b opened at the side end of the leg shield 22a. Then, the traveling wind (rear flow) Uw that has been jetted merges with the front flow Fw that has passed over the side end of the leg shield 22a, so that the negative pressure generated on the rear surface of the leg shield 22a is reduced. As a result, the force that winds the front flow toward the rear side of the leg shield 22a is weakened, so that the front flow Fw flows backward without flowing around from the periphery of the leg shield 22a. From this, the windshield effect on the leg Ma of the driver M is enhanced. Since the windshield effect is high, it is not necessary to provide a windshield device protruding from the scooter 1. Since there is no protruding windbreak device, the external shape and dimensions of the scooter 1 do not change. Therefore, it is possible to suppress an increase in the size of the scooter 1, to enhance the appearance, and to enhance the windshield effect on the leg Ma of the driver M. Can be. Further, the front flow Fw does not flow from the periphery of the leg shield 22a but flows backward without change, so that the windshield effect on the legs of the fellow passenger is enhanced. For this reason, the driver and the passenger can obtain comfort.
