A fence panel for a vehicle, wherein a fence panel for preventing falling objects is provided between the rear flanges of the columns.

Further, a vertical lattice portion is provided between the main rail and the auxiliary rail of the protective fence or the fence integrated type protective fence.

As a mechanism for mounting the main rail and the auxiliary rail on the main rail receiving portion and the auxiliary rail receiving portion, a bolt hole is formed in the rail receiving portion and the auxiliary rail receiving portion, and the main rail and the auxiliary rail receiving portion are mounted with fastening bolts.

The fence panel uses a transparent synthetic resin material such as a polycarbonate plate or a wire mesh, and is appropriately selected according to the road conditions, the use of the windproof plate, the snowproof plate, and the like. Things.

In the present invention having such a configuration, the struts are formed in an arc shape toward the outer side of the road, so that the road width is felt wider and the feeling of pressure is reduced as compared with the conventional upright type struts.

Further, since the main rail receiving portion and the auxiliary rail receiving portion are horizontally protruded from the column main body, the position and diameter of the main rail receiving portion and the number of the auxiliary rail receiving portions vary depending on the road type. If so, each of the main rail receiving portion and the auxiliary rail receiving portion may be replaced, and it is not necessary to make a mold of the entire support body.

In the case of a protective fence integrated with a fence, since the column is extended upward, there is no sense of incongruity that only the part is replaced, and the protective fence is further formed in an arc shape outward. Therefore, there is no feeling of oppression and the design is excellent.
