摘要:
Provided is a different materials panel structure having reduced occurrence of displacement or warping of a joining section and having excellent external appearance of an outer panel (2). The different materials panel structure has: an outer panel comprising a first metal material; an inner panel (3) arranged on the lower surface side of the outer panel and comprising a second metal material having a higher fusion point than the first metal material; and a rivet (6) comprising the same material as the second metal material and comprising a head section and a shaft section. An outer panel comprises a hemmed section formed by folding a rim section and which supports the inner panel via an adhesive layer (9). The head section of the rivet remains on the outer panel surface. The shaft section of the rivet penetrates from the lower surface side of the hemmed section of the outer panel towards the inner panel. A tip of the shaft section is spot-welded to the inner panel and a protruding section (3a) is provided in the inner panel at a position corresponding to the rivet and protruding in the axial direction of the rivet. A heat insulation section (8) comprising the adhesive layer or the adhesive layer and a gap is formed between the protruding section after welding and the outer panel.
