<p>Deformation of a trunk door is suppressed with a simple structure. A lateral bead (38) is formed along a ridgeline region (37) that is formed by an inner upper wall portion (30) and an inner rear wall portion (32) of an inner panel (20) of the trunk door (14). The lateral bead (38) is not connected to a ring bead (34) formed at an outer periphery of the inner panel (20). Thus, stiffness of the ridgeline region (37) may be suppressed compared with a case in which the lateral bead (38) is connected to the ring bead (34). Thus, substantial V-form folding of an outer upper wall portion (24) and an outer rear wall portion (26) may be suppressed. This substantial V-form folding occurs, in a state in which a middle portion of a vehicle rearward lower side of the trunk door (14) is fixed by a lock assembly (42) and a striker of the vehicle, when an upward turning force F from door hinges (16) at each of two vehicle width direction sides acts at the vehicle forward side of the two vehicle width direction sides and a reaction force acts from weatherstripping.</p> |
