Claims

[Scope of utility model registration request]

In a joint structure in which the inner plate edge of a double sheet metal for automobiles is folded back and sandwiched between the outer plate edges and joined together, a cut-and-raised protrusion is provided on the inner plate edge by press working, and the folded surface of the outer plate edge is A notch or punched hole is provided at the position opposite to the cut-and-raised protrusion on the inner plate edge into which the cut-and-raised protrusion fits, and when the outer plate edge is folded back and overlapped with the inner plate edge. A joining structure for a double sheet metal edge for an automobile, characterized in that a raised projection protruding from a notch or punched hole is bent and joined.
