Abstract
A back door structure for a motor vehicle in which a back door is hingedly mounted on a vehicle roof for movement between an open and closed position. The back door is of trapezium configuration, with its lower portion wider than its upper portion. A stay damper is connected with the back door at one end and connected with a rear pillar at the other end. The stay damper biases the back door to a raised open position and is disposed between the rear pillar and the back door when closed. The stay damper moves outwardly in accordance with the opening of the back door. The back door includes a frame member disposed along the side peripheral edges of the back door window glass. A conceal member is connected with the frame member and extends outwardly, forming the rear corners of the vehicle body and concealing both the stay damper and the rear pillar. The conceal member constitutes a portion of the outer surface of the vehicle body. The side margins of the window glass are extended to the outside of the back door frame member so the car design becomes more flexible. Moreover, the rear pillar is covered by the conceal member, and the vehicle appearance is greatly improved.
