## Abstract

A fastener constituting an essential part of a fixing structure for fastening a radiator grille to an automobile body is provided on one side of the base plate portion thereof with fastening means for engagement with the automobile body and on the other side of the base plate portion with fastening means for engagement with the radiator grille and additionally with a rib in a position surrounding the radiator grille fastening means which rib is tightly accommodated into a recess formed in the radiator grille fastening portion. This arrangement gives the fastener enhanced resistance to various forms of stress that may be exerted on the radiator grille in use.
