Connecting structure of metal plates |
摘要 |
Provided is a connecting structure in which it is difficult for a crack to occur, even if a connection location is set in a portion on which concentrated tensile stress may occur. Laminated metal plates are concurrently punched out downward in shape of tongue piece. A depth of punch-out is not smaller than a total thickness of the laminated metal plates. A tongue piece portion is punched out in shape of cantilever beam while a central connection portion is left behind. The tongue piece portion is bent downward in the out-of-plane direction at a connection portion linking to the central connection portion in order that a location of the tongue piece portion in the extension direction on its way is parallel to a bend line. The tongue piece portion is configured to widen in width gradually toward a front end thereof. |
