Abstract

See full text

An inner panel of a vehicle hood has a 0.2% proof stress of 70 MPa or more and 120 MPa or less after assembling of the inner panel and completion of bake coating. An outer panel has a 0.2% proof stress of 150 MPa or more. The outer panel is made of JIS 5000 or 6000 series aluminum alloy plate material, and the inner panel is made of a JIS 3000 series aluminum alloy plate material. The inner panel has hat-shaped main beads arranged in a center portion. An elongation amount (L−L0)/L0 determined by cross-section line length L of a concave or convex portion of the main bead projected from the surface of the center portion and a line length L0 of a line segment linearly connecting ends of the portion is 0.4 δ to 0.6 δ to a breaking elongation δ in uniaxial tensile deformation.
