Abstract: In a molding fixing structure, a T-stud stood within a roof groove is inserted into a T-stud insertion hole of a fixing clip, and then a roof molding is moved in a longitudinal direction of the roof groove with respect to the T-stud to insert the T-stud into a T-stud fixing hole of the fixing clip. A base plate portion of the fixing clip includes a bottom portion positioned lower than a lower surface of a head portion of the T-stud when the T-stud is inserted into the T-stud insertion hole, a guide portion that extends obliquely upward from the bottom portion toward a longitudinal center side of the roof molding and is in sliding contact with the lower surface of the head portion of the T-stud, and a top portion formed in the guide portion and positioned higher than the lower surface of the head portion.

Abstract: Disclosed is an automotive floor panel assembly, in which the floor panel assembly is stamp formed into a prescribed shape from at least one piece of sheet metal blank which consists of a first panel section made of sheet metal stock of a first thickness, and a second panel section made of sheet metal stock of a second thickness which are butt welded to each other along opposing edges thereof by using a high energy beam. Because the butt welding is carried out on flat panels, welding quality can be maintained at a high level without any substantial difficulty, and the resulting blank can have a highly uniform finish even though it includes a plurality of parts having different thicknesses. By suitably arranging the various parts having different thicknesses to different parts of the floor panel assembly in an optimum fashion, it is possible to achieve a maximum mechanical strength and a maximum rigidity with a minimum amount of material or involving a minimum weight.
