Abstract: Deformation of a trunk door is suppressed with a simple structure. A lateral bead is formed along a ridgeline region that is formed by an inner upper wall portion and an inner rear wall portion of an inner panel of the trunk door. The lateral bead is not connected to a ring bead formed at an outer periphery of the inner panel. Thus, stiffness of the ridgeline region may be suppressed compared with a case in which the lateral bead is connected to the ring bead. Thus, substantial V-form folding of an outer upper wall portion and an outer rear wall portion may be suppressed.
