DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a front cowl for covering a front portion of a three-wheeled vehicle having two front wheels and one rear wheel.

[0002]

2. Description of the Related Art Conventionally, Japanese Utility Model Publication No. 39-9805 is disclosed as a three-wheeled vehicle having two front wheels and one rear wheel. This technology relates to a "golf car" in a three-wheeled vehicle with two front wheels and one rear wheel. The three-wheeled vehicle disclosed in this technology is:
A front cowl is provided to cover the front part of the vehicle. The front cowl is provided from the front to the rear of the front wheel, and the rear part of the front cowl is configured to be located at a position behind and behind the front wheel. The floor is provided rearward from the rear end of the front cowl. Further, the footrest portion of the occupant is arranged in front of a space surrounded by a deep front cowl, while the rear end of the front cowl faces the rear of the front wheel, and a seat post portion is arranged immediately after.

[0003]

In the above-mentioned conventional three-wheeled motor vehicle, the rear end of the front cowl is located at a position behind and behind the front wheels.
The front cowl has a deep space formed in the front, while the space on the floor opened to the side between the seat post portion and the rear end of the front cowl becomes shorter in the front-rear direction. Therefore, the footrest portion of the occupant must be disposed forward in the front cowl, and the distance between the rear end portion of the front cowl and the seat post portion is short. In particular, in this type of vehicle, it is necessary to be able to get on and off easily without getting caught on the foot and paying special attention to getting on and off,
Also, it is extremely preferable to be excellent in getting on and off.

[0004] Further, since the front cowl is provided from the front to the rear of the front wheel, the entire shape of the front cowl becomes large, and the front cowl is often formed of resin, so that the formability of the front cowl is poor. , There is also a disadvantage. Furthermore, it is necessary to provide front fenders on both sides of the front cowl to cover the left and right front wheels,
When installing the front fenders on both sides of the front cowl, the front cowl needs to be provided separately from the front cowl because the front cowl becomes large as described above, which increases the number of parts and the number of assembly steps. Increases, and the like.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the present inventors have proposed a tricycle having a front cowl at a front portion of a vehicle and a seat post on a floor. How to keep it good, how to get the front cowl that effectively covers the front part of the vehicle including the front wheel, and how to make the front cowl formable, The present invention has been made to solve these problems in consideration of how to obtain a good and functionally sufficient front fender without making the covering front fender a separate component. It is.

[0006] Therefore, the object of the present invention is to provide an extremely excellent occupant getting on and off and excellent front cowl moldability.
Another object of the present invention is to provide a front cowl of a three-wheeled vehicle, which is convenient for installing a front fender.

[0007]

In order to solve the above-mentioned problems, in claim 1, two front wheels and one rear wheel are provided.
Equipped with a floor that constitutes steps, etc., where the occupant sits
A seat, the vehicle body front, in three-wheeled vehicle comprising a front cowl that covers a front portion of the vehicle body, the front Cow

Equipped with a rear body and provided on both sides of the front cowl
Both the rear end of the front half of the front fender and the floor
Connects to the front end of the rear half of the front fender provided on the side
And form a front fender that covers the two front wheels,
The front cowl has the rear ends on both sides
Located approximately above the axle of the wheel and the front cowl
The front end face was located in front of the front wheels.

Accordingly, since the rear ends of both sides of the front cowl are located substantially above the front wheel axle, even if the seat post portion is arranged on the floor and the front cowl is arranged in front of the seat post. The space between the rear end of the front cowl and the seat post can be made larger to improve the ease of getting on and off the floor-footed tricycle, and to reduce the front-rear dimensions of the tricycle to reduce its size. it can. In addition, the formability of the front cowl can be improved while effectively covering the front portion of the vehicle including the front wheels. More front wheels
Separate front fender from front cowl and floor
Good and functional enough without individual parts
A front fender can be obtained.

According to a second aspect, in the first aspect,
The front cowl has fronts with the upper part inclined backward.
Provide a clean screen and make sure that
A roof is provided from the rear to the rear, and a support
To support it .
