This is a license plate mounting structure in which a retainer is mounted on the back side of the plate mounting portion, and a license plate is screwed into the license plate mounting portion of the bumper with a nut interposed on the rear surface of the retainer. When molding the bumper on the back surface of the license plate mounting portion of the bumper, for example, a rib is provided in advance by integral molding, a claw engaging with this rib is provided on the retainer, and the claw is engaged with the rib. The retainer is mounted on the back of the bumper. The ribs of the bumper are thin and are provided at a certain interval in the vertical direction of the bumper. A plurality of claws opposed to each other are provided on the retainer on both sides in the vehicle width direction of the ribs so as to correspond to the ribs, and the retainers are assembled to the ribs between the claws. The retainer has a hole for passing a screw at a position corresponding to the mounting hole of the bumper. A nut is attached corresponding to this hole. Guide portions engaging the ribs are provided on the upper and lower surfaces of the ribs, and these guide portions are engaged with the upper and lower surfaces of the ribs to position the retainer vertically.

[0010] Thus, when installing the domestic license plate, the license plate is attached using the normal license plate attachment portion provided for attaching the domestic license plate. On the other hand, when the export license plate is attached, the export license plate is attached. A mounting hole is formed at the mounting position of the license plate, and a retainer is mounted using a rib of a bumper formed at the position of the mounting hole. Then, a screw is screwed into a nut arranged on the rear surface of the retainer, and an export license plate is attached. The ribs provided on the bumper are thin and are provided along the material flow direction (vehicle width direction) at the time of the bumper forming process, so that the occurrence of sink marks is reduced. Therefore, the appearance can be improved. In particular, the number of components is smaller than that of a structure in which a license plate for export is attached using a bracket, and there is no bracket outside the bumper, so that the appearance can be improved.

[0011]

Embodiments of the present invention will be described below in detail with reference to the drawings.

In FIG. 1, a bumper 1 is formed such that a domestic license plate and an export license plate can be attached as required.
