BONDING STRUCTURE FOR METAL PLATE

摘要

Provided is a bonding structure for a metal plate, cracking of the plate is hardly caused even when a bonding position is set on a portion where a tensile stress is concentrated. Laminated metal plates are blanked together toward the lower surface sides thereof and formed into a tongue piece shape. The depth of blanking is made to be equal to or more than the total of the laminated metal plates. Tongue piece parts (8) are blanked in a cantilever shape with a bonded center part (3) side being left. The tongue piece parts (8) are so bent in the outer and lower direction at the connection portions thereof with the bonded center part (3) that the intermediate positions of the tongue piece parts (8) in the extending direction are parallel with the folding lines (7) of the connection parts. The width of each of the tongue piece parts (8) is so set as to gradually increase toward its tip end.
