Therefore, for example, the hexagonal vertex portions at the projecting ends of the hexagonal cylindrical ribs formed on the inner wall surface of the inner panel can be effectively joined to the inner wall surface of the outer panel by vibration welding or the like.

According to the third invention , on the inner wall surface of either one of the inner panel and the outer panel, the hexagonal cylindrical rib formed between the adjacent plate-shaped ribs has a protruding end side that is closer to the one inner wall surface side. It is constructed to be thin. Therefore, when the hexagonal cylindrical rib is injection-molded on the inner wall surface of either the inner panel or the outer panel, molding defects of the hexagonal cylindrical rib can be suppressed.

According to the fourth invention , the vertex portions of adjacent hexagonal cylindrical ribs are connected by connecting ribs. Therefore, the strength of the door portion can be further improved.

According to the fifth invention , the plate-like rib and the hexagonal cylindrical rib are formed on the inner wall surface of the inner panel of the door portion. Therefore, the shape of the outer panel side of the door portion is simplified, and the shape accuracy of the design surface can be improved.
