Joint construction for metal sheets.

摘要

A joint construction for metal sheets (1, 2) which is made by joining first and second metal sheets by utilizing plastic working. The first metal sheet (1) is formed with first cut-up pieces (4) to have openings therein. A portion of one end edge of the second metal sheet partly superposed on the first metal sheet is held between the openings and the first cut-up pieces and in this state it is pressed along with the cut-up pieces so that the portion is pressed into the openings. The portion of the second metal sheet (2) pressed into the openings is locked by the peripheral walls of the openings.
