DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front hood, and more particularly to a front hood mounted on the front of a driver's seat of a working vehicle.

[0002]

2. Description of the Related Art Various members necessary for driving operation are installed in front of a driver's seat of a working vehicle. A column frame is erected on a floor panel, and operation pedals such as an accelerator pedal and a brake pedal are attached. A handle post is attached to the column frame, and a handle is attached to an upper portion of the handle post. Then, a lower front hood is mounted on the front surface of these members to cover each member.

On the other hand, a meter panel is provided on the upper part of the column frame, and an upper front hood is mounted on a front surface thereof to cover the meter panel.

[0004]

The front hood mounted on the front of the driver's seat of a conventional working vehicle is divided into a lower front hood and an upper front hood.
When performing maintenance on each member installed in the driver's seat, the lower front hood and the upper front hood must be separately removed, and the attaching and detaching work is complicated.

[0005] Therefore, there arises a technical problem to be solved in order to simplify the structure of the front hood and facilitate maintenance, and an object of the present invention is to solve this problem.

[0006]

SUMMARY OF THE INVENTION The present invention has been proposed to achieve the above object, and is a front hood mounted on the front of a driver's seat of a working vehicle, wherein a meter is provided at an upper portion of the front hood. A front hood in which a panel is covered and a floor panel, a column frame, an operation pedal and the like are covered at a lower portion of the front hood, and an upper portion and a lower portion of the front hood are integrally formed. .

[0007]

[Function] Among the members installed in the driver's seat of the working vehicle,
The front panel of the floor panel, column frame, operation pedal, and the like is covered by a lower portion of the front hood.
Further, the front surface of the meter panel disposed on the column frame is covered by the upper portion of the front hood.

Since the upper and lower parts of the front hood are integrally formed, when the members are to be maintained, all the members are exposed by removing the entire front hood, and the maintenance is extremely reduced. Easy to do.
