Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has four wide ultra-low pressure tires (balloon tires), a bar handle and a saddle-riding type seat, and is capable of running on rough terrain such as rough roads and wetlands. The present invention relates to a fender structure for a traveling vehicle.

[0002]

2. Description of the Related Art Conventionally, when a carrier for loading luggage is provided in front of and behind the vehicle traveling on an uneven terrain, a carrier made of a pipe is disposed above a front fender or a rear fender and is fixed to a frame. It is common to provide it independently. Further, a method has also been proposed in which a carrier is integrated with a front fender or a rear fender and the fender itself is used as the carrier.

[0003]

However, among the above-mentioned conventional methods, the method of independently providing the carrier has a problem that the increase in the number of parts and the weight leads to an increase in cost and a decrease in designability. In addition, in the method of integrating the fender and the carrier,
This causes problems in rigidity and supporting strength as a carrier.

The present invention is intended to solve the above-mentioned problems. By integrating the fender and the carrier, it is possible to reduce the weight and the number of parts, and to improve the rigidity and the supporting strength of the carrier. An object is to provide a fender structure for a ground level vehicle.

[0005]

To this end, the vehicle fender structure of the present invention is a vehicle body with a vehicle body frame 1 in an all-terrain vehicle having four wide ultra-low pressure tires, a bar handle 10 and a saddle type seat 12. Support members 15 and 25 fixed to the support members 15 and fenders 17 and 26 attached to the support members 15 and 25, and a mountain surface 17a and a valley portion 17b are continuously formed on a carrier surface on which the load of the fender is placed. And a large number of reinforcing ribs 17c are provided on the back side of the mountain portion 17a.
Is integrally formed. The numbers added to the above configuration are for comparison with the drawings,
This does not limit the structure of the present invention.

[0006]

In the present invention, since the front fender 17 and the rear fender 26 are fixed to the upper frame 1 via the supporting members 15 and 25, the supporting strength as a carrier can be ensured, and the fender The carrier surface on which the luggage is placed has a mountain portion 17a and a valley portion 17b formed continuously, and a large number of reinforcing ribs 1 are provided on the back side of the mountain portion 17a.
Since 7c is integrally formed, the rigidity as a carrier can be secured.
