  • Patent number: 8220855
    Abstract: A tailgate structure having a tailgate (17) composed of an outer panel (31), a frame (32), and a lining (33); and a lock mechanism (43). The frame has an opening (61) formed between the lock mechanism and a mounting hole (35) for an externally mounted component, the hole being formed in the outer panel. The lining has a protrusion (68) that protrudes toward the exterior of the vehicle. The protrusion is positioned on a line that connects the mounting hole and the lock mechanism. When a rod-shaped member is inserted into the tailgate from the mounting hole, the rod-shaped member will come into contact with the protrusion and will not reach the lock mechanism.
