0 is attached.

Reference numeral 22 denotes a unit swing type power unit in which a forced air cooling type two cycle upright type rear wheel drive engine 24 and a transmission case 26 are integrally assembled, and a side surface (FIG. 1) and a plane surface (FIG. 2). ), It is formed in a substantially L shape. That is, the engine 24 is located in front of a rear wheel 28 attached to the rear wheel of the transmission case 26, and includes a cantilevered crankshaft 30 that is horizontally placed, and a piston 32 that tilts slightly backward and moves vertically.

On the side opposite to the transmission case 26 of the engine 24,
An intake air purifier 34 is attached. This intake cleaner 3
The first and second chambers 3 are provided on the left and right sides by the filter 36 in the chamber 4.
8a and 38b are defined, and the second chamber 38 is provided in the first chamber 38a.
A carburetor 40 is arranged so as to connect b with the crank chamber. As a result, the intake port 4 formed in the first chamber 38a
The intake air that has entered the first chamber 38a from 2 is a filter 36, a second chamber 38b, a carburetor 40, and a reed valve (not shown).
Is sucked into the crank chamber.

The front end of the power unit 22 is vertically swingably connected to the side tube 16, and the rear part thereof is elastically supported by a buffer unit 44.
The side tube 16 extends to a height near the upper edge of the rear wheel 28, and a battery 46, a lubricating oil tank 48, and a storage case 50 are arranged above the side tube 16.

[0012] 52 is a footrest of the low floor type substantially plate shape, its
Has a flat footrest surface. The footrest 52 is provided on the lower end of the down tube 14 and the side tube 16.
It is made to cover the front part of the. 54 is a rear cover, toward the rear of the foot location surface on the periphery of the below driver's seat 56
Thus, the power unit 22 and the rear wheel 28 are covered with the battery 46, the oil tank 48, and the storage case 50. An operating seat 56 is attached to the upper portion of the rear cover 54 so as to be openable and closable.

Reference numeral 58 denotes a fuel tank, which has a side surface substantially L so that it can be inserted from the inside of the footrest 52 to the inside of the rear cover 54.
It is shaped like a letter. That is, the portion 58 in the footrest 52
a is a substantially horizontal plate shape, and the portion 5 in the rear cover 54
8b stands up along the side tube 16. An oil supply port 58c is formed in the upper portion of the inner portion 58b of the rear cover 54 so as to be directed obliquely upward and forward, and a cap 60 is attached thereto.

The inner portion 58 of the footrest 52 of the fuel tank 58
An electromagnetic fuel pump 62 is attached to the bottom surface of the. The fuel pump 62 sends the fuel in the tank 58 to the vaporizer 40. The rear cover 54, which is a standing wall that rises from the rear of the footrest 52 toward the lower surface of the front of the driving seat 56, has a portion facing the cap 60 that serves as a lid plate 64 that can be opened and closed forward. There is. The lid plate 64 is opened and the cap 60 is removed to refuel.

According to this embodiment, since the fuel tank 58 is provided on the footrest table 52, its capacity can be increased, and at the same time, the center of gravity can be lowered. Further, since there is no fuel tank under the operation seat 56, the capacity of the storage case 50 can be increased. Although a part of the fuel tank 58 extends into the rear cover 54, the heat of the engine 24 is less likely to stay in the vicinity of this part 58b, so that the tank 58 is not overheated or the amount of fuel evaporation is not increased. Further, since the tank 58 is L-shaped and greatly bulges not only in the footrest 52 but also in the rear cover 54, the tank 58 can have a significantly large capacity.

However, since the volume of the portion 58a in the footrest 52 is large, the center of gravity of the vehicle becomes low and the running stability is good even when the tank 58 is filled with fuel. Further, since the inner portion 58b of the rear cover 54 is erected upward, the refueling port 58c provided at the upper portion is also raised, and refueling can be performed in a comfortable posture without significantly bending the body during refueling. Particularly, since there is a large space above the footrest 52 in front of the fuel filler port 58c, workability is further improved. Further, unlike the case where the capacity of the fuel tank facing the seat bottom plate is increased, the seat does not become taller even if the capacity of the fuel tank is increased.

FIG. 3 is a side view of a portion of another embodiment.
In this embodiment, the fuel tank 58 in the embodiment of FIGS. 1 and 2 is divided into two. That is, the fuel tank 70 of this embodiment is divided into the inner portion 70a of the footrest 52 and the inner portion 70b of the rear cover 54.
70b is connected by the pipes 72, 72. Further, 70c is a fuel filler port. The storage case is, of course, arranged below the operation seat 56 as in the embodiment shown in FIGS.

According to this embodiment, since the tank 70 can be divided into a plurality of parts and arranged, the degree of freedom in arrangement is increased and the fuel is moved back and forth during acceleration / deceleration without providing partition walls in the respective parts 70a and 70b. Can be suppressed. In FIG. 3, the same parts as those in FIG. 1 are designated by the same reference numerals, and the description thereof will not be repeated. Although each of the above embodiments is a two-wheel scooter, the present invention can be applied to a scooter having three or more wheels.

[0019]

As described above, according to the present invention, the upper surface of the footrest is
While the flat fuel tank is arranged, the storage case is arranged between the power unit arranged at the rear of the footrest and the operation seat above it. Therefore, the fuel tank and the storage case are respectively provided. The capacity can be increased.
Especially, since the position of the fuel tank is low, the center of gravity of the vehicle body can be lowered. Also because there is no fuel tank under the driver's seat, fuel
There is no risk of soiling the luggage case or luggage. More legs
Since the top surface of the stand is a flat foot rest surface, it is easy to place your feet on it.
