摘要： An aluminum roof outer panel (2) is spot welded to a roof side rail (3) consisting of galvanized steel sheet. The outer panel (4) of the roof side rail is made of galvannealed steel sheet that has a favorable property but cannot be favorably welded to the aluminum roof outer panel, but the inner panel (5, 6) of the roof side rail is made of non-galvannealed steel sheet that can be favorably welded to the aluminum roof outer panel. Flanges of the outer panel (4) and inner panel (5, 6) overlap each other, and the flange of the outer panel is provided with a plurality of notches (11) along an edge of the outer panel. A corresponding flange of the roof outer panel is welded to the parts of the inner panel exposed by the notches of the outer panel.
