Patent ID: 8434815

Claim:
A vehicle inner panel which, together with an outer panel, forms a vehicle hood, comprising: a reference surface; and a plurality of beads having at least convex or concave cross-sections with respect to the reference surface, the plurality of beads being formed parallel with one another and extending in a longitudinal direction of the vehicle, wherein: the reference surface surrounds the plurality of beads; each bead includes a vertical wall, a lower flange that extends from a bottom edge of the vertical wall, and an upper flange that extends from an upper edge of the vertical wall; the vertical wall, the lower flange, the vertical wall, and the upper flange are shaped so as to be successively connected at a cross-section orthogonal to the direction in which the beads are lined up; the vertical wall is formed from an upper vertical wall and a lower vertical wall that is below and bent with respect to the upper vertical wall; an inclination angle of the upper vertical wall with respect to the upper flange is greater than an inclination angle of the lower vertical wall with respect to the upper flange; a bent portion between the upper vertical wall and the lower vertical wall of the beads is positioned more than half way between the lower flange and the upper flange so as to be closer to the upper flange than the lower flange and partially extends continuously in a straight line shape along a longitudinal direction of the bead; and the upper flange is joined to the outer panel.
