Abstract
Abstract Disclosed are a roof panel and a rear fender outer panel have flange portions, respectively. The flange portions define sides of a back door receiving opening. The roof panel and the rear fender outer panel are respectively fitted with support members which are constructed and arranged to cooperate with the flange portions, a weather strip and a frame of a back door assembly to define adjacent said receiving opening a drip trough the depth of which is larger than its width. The frame of the back door assembly is constructed and arranged to have a box-like section including a bottom side and to engage the weather strip at the wall portion defining the bottom side whereby the frame is markedly reduced in width, resulting in an increased vision area of a glass panel of the back door assembly and therefore an improved visibility as well as an improved appearance.
