[Example 1 Examples will be described below based on the accompanying drawings.

FIGS. 1 and 2 show an example of a running vehicle to which the present invention is applied.
In the figure, the traveling vehicle is a three-wheeled motor vehicle l, and this three-wheeled motor vehicle l consists of a front body 2 and a rear body 3.

The front body 2 has a low-floor structure similar to that of a scooter, with a front fender section 4 at the very front and a front section 5 that slopes diagonally rearward and downward from the rear of the fender section 4. A floor part 6 is provided which extends flatly rearward at a low position from the rear end. The floor part 6 is configured to rest the left and right feet, and a box-shaped raised wall part 7 is provided at the rear of the floor part 6 so as to cross the center part in the width direction. to prevent
It functions as a foot guard to prevent the feet from interfering with the swinging rear vehicle body 3.

A support post 9 for a front fork 8 is installed on the front part 5 of the front vehicle body 2, and the front fork 8 is installed longitudinally through the support post 9. A front wheel 10 forming one steering wheel is supported. A bar handle 11 is provided at the upper end of the upwardly extending portion of the support post 9 of the front fork 8, and a case 12 for storing and supporting a headlight and instruments is provided at this portion. Further, a seat post 13 is provided on the central portion of the raised wall portion 7 at the rear of the front vehicle body 2, and a seat 14 for a passenger is placed on the post 13.

A rear subframe 17 extends rearward on the rear lower surface of the front vehicle body 2, and a rear fork 1 is attached to this rear subframe 17.
8 are pivotally connected to each other so as to be able to swing up and down using a pivot pin 19 as a fulcrum. And on the rear fork 18 is the engine 2.
0, a case 21 containing a crankcase, transmission, and deceleration mechanism is installed, and a drive unit 22 including these is disposed between rear wheels 23 and 23 forming two drive wheels. The drive unit 22 is housed within the outline of the rear wheel 23, and is therefore hidden from the side by the rear wheel 23. The muffler 24 is also housed within the outline of the rear wheel, and furthermore, above the left and right rear wheels 23.23. A rear fender member 25 is provided to cover the upper side of the drive unit 22.

A convex portion 132 having a box-shaped cross section and a predetermined width is provided in the widthwise central portion of the floor portion 6 of the front vehicle body 2 in the longitudinal direction. Footrests 106, 106 are formed on the left and right sides of the convex portion 132, and the width of the footrest 106106 is set to a width necessary and sufficient to place the feet. In addition, the front part of the footrest part 106 is
As shown in the figure, it is inclined forward and upward along the front part 5 of the vehicle body. The front part of the footrest section 106, which is tilted upward, allows the occupant to stretch out his or her feet and place them thereon, thereby improving the footrest.

And the floor i'fl between the left and right footrests 106, 106
As shown in the figure, a battery 30. A fuel tank 26 is housed at the rear. By housing the fuel tank 26 in the box-shaped space of the convex part 132 formed in the center of the floor part 6 between the left and right footrests 106, 106, the fuel tank 26 can be protected from above. Of course,
Protection from both the left and right sides is also provided.

Here, the injection cap 27, which is the fuel injection part of the fuel tank 26, protrudes upward from the upper surface 132a of the convex part 132. In particular, the injection cap 27 is brought close to the raised wall part 7 and placed below the front end of the seat 14. It is positioned so that it faces you.

By the way, the convex portion 132 has a structure as shown in cross section in FIG. That is, FIG. 3 shows that the front dL body 2 is constructed of a pipe frame 202, and the pipe frame 202 extends in the front and back direction with left and right pipe elements 202a, 202a spaced apart from each other to the left and right. A pair of foot rests 206 and 206 are disposed, and a space 233 is formed therebetween. A fuel tank 26 is disposed within this space 233, and a lower portion of the fuel tank 26 projects below the pipe elements 202a, 202a. and an undercover 23 that covers the space 233 from below.
4 is provided, and this under cover 234 is
Pipe element 202a with both left and right ends tied to 6,206,
202a is sandwiched therebetween. An upper cover 235 is provided to cover the space 233 from above. Further, the front part of the undercover 234 is inclined upwardly toward the front along the front part 5 of the vehicle body, as shown in FIG. This under cover 234
In addition to protecting the fuel tank 26 etc. from the road surface, the under cover 23 slopes upward in front of it.
4 The front section also protects the vehicle from obstacles on the road from the front, from climbing over curbs, and from flying stones.

The tricycle 1 with the above configuration has a floor located in front of the pivot joint between the drive unit 22 of the rear wheel 23 and the front vehicle body 2, that is, the joint between the rear foot frame 17 and the rear foot frame 17 by the pivot pin 19. Since the fuel tank 26 is disposed on the side of the section 6, there is no need to worry about the tank 26 being heated by the engine 20, the center of gravity of the vehicle body is lowered, and the rocking displacement of the connection position of the rear wheel drive unit 22 on the vehicle body side is reduced. Since the amount is small, it is also possible to increase the tank capacity by moving the rear surface of the tank 26 closer to the engine 20 side.

Furthermore, since the fuel tank 26 is attached to the rear part of the floor part 6, the rigidity of the vicinity of the rear part of the front vehicle body 2, which connects and supports the rear wheel drive unit 22, is also improved.

Particularly, in the tricycle l to which the present invention is applied, the filling cap 27 of the fuel tank 26 disposed at the rear of the floor section 6 is located near the lower part of the front of the seat 14, that is, between the left and right footrests fi106, 106. Since the filler cap 27 is located at the rear of the vehicle near the seat 14, the rider can remove the filler cap 27 from behind his or her feet while placing his/her feet on the footrests 106, 106, and fill the tank 26 with fuel. can be easily replenished.

Moreover, since the injection cap 27 is located at the rear end of the convex portion 132 that the occupant straddles when getting on and off the vehicle, the injection cap 27 does not get in the way of the legs.

In the embodiment, an example of application to a three-wheeled motor vehicle has been described, but it goes without saying that the present invention can also be applied to a two-wheeled motor vehicle.

[Effects of the Invention] As described above, according to the present invention, a low-floor footrest is provided between the front wheel and the rear wheel, a seat is provided above the rear part of the footrest,
In addition, in a traveling vehicle in which a fuel tank is disposed in a footrest, the filling part of the fuel tank disposed in the one-footrest is located near the lower part of the front of the seat, so that the one-footrest can be improved. Since the injection part is located at the rear near the seat, it is easy for the occupant to refuel with their feet on the footrest.
