Claims

[Claims for Utility Model Registration] (1) In a state where the second thin metal plate is sandwiched between the folded portion formed by bending the first thin metal plate, the first thin metal plate and the second thin metal plate are In the metal thin plate joining structure in which two metal thin plates are joined, one side of the folded portion of the first metal thin plate and the second metal thin plate are joined.
A series of through holes are formed in the thin metal plate, and a joining piece to be inserted into the through hole is formed integrally with the first thin metal plate on the other side of the folded portion of the first thin metal plate. A joining structure for thin metal plates, characterized in that the tip of the joining piece is bent along the outer surface of the one side. (2) The metal thin plate joining structure according to claim 1, wherein the edge portion of the second metal thin plate abuts on the inside of the folding line of the folded portion. (3) The joining piece contacts the peripheral edge of the through hole on the side where the folding line of the folded portion is located, as claimed in claim 1 or 2 of the utility model registration claim. The bonded structure of the metal thin plates described. (4) The joining piece contacts the peripheral edge of the through hole on the side opposite to the side where the folding line of the folded portion is located, Claim 1 of the Utility Model Registration Claim. Or the joining structure of thin metal plates according to item 2. (5) The joining of thin metal sheets according to any one of claims 1 to 4 of the utility model registration claims, wherein the joining piece is formed by cutting and raising a part of the first thin metal sheet. structure.
