Description

  The present invention relates to a resin-made fender panel mounting structure.

  Generally, a fender panel is attached to the front side surface of the automobile, which is located on the front wheel and forms an outer plate. Conventionally, sheet metal has been the mainstream for fender panels. However, in recent years, the number of fender panels formed from resin is increasing from the viewpoint of weight reduction of fender panels, protection of pedestrians, and design formation. An example of such a resin fender panel is disclosed in Patent Document 1 below.
