[0014]

As described above, according to the structure of the bumper grille opening of the present invention, the following effects can be obtained. The structure of a bumper grille opening according to claim 1, wherein the front bumper is provided with a grille opening for taking in air for cooling the radiator. In the structure of the bumper grille opening, a grill net is provided on the back surface of the grille opening. Since the bumper brace that reinforces the grill opening is arranged on the back side, the rigidity of the grill opening can be improved, and the appearance is improved because the bumper brace cannot be seen from the front side of the bumper. Can be achieved. In the second aspect, since the grill net and the bumper brace are fixed to the upper and lower portions of the grill opening, the grill opening can be prevented from being deformed, and the appearance can be improved. In the third aspect, the bumper brace is fastened together with the grill net, so that the number of fixed parts of the bumper brace can be reduced and the cost can be reduced. In claim 4, since the upper portion of the bumper brace is extended and fixed to the back surface of the front bumper above the grill opening, the rigidity of the grill opening can be improved.
