Abstract From the Canadian patent

The present invention relates to a vehicular trunk lid structure formed by overlapping the end of the outer panel upon the end of the inner panel, to be followed by a hemming process wherein recesses are defined adjacent to the end of the inner panel, the recesses being deepened toward and welded to the outer panel. By such arrangement, the weld bead due to the spot-welding is concealed inside the trunk room to be obscured from the outside and thus the need of finishing work to remove the weld bead is eliminated. As a consequence, an aesthetic improvement and a manufacturing cost reduction are accomplished.
