Abstract: A vehicular trunk lid structure is formed by overlapping the end of the outer panel upon the end of the inner panel, to be followed by hemming process, wherein recesses are defined adjacent to the end of said inner panel, and said recesses are deepened toward and welded to said 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.
