Abstract
A vehicle door structure including a door panel assembly made of an outer panel of a plastic material and an inner panel of a plastic material which are connected together at front, rear and lower edge portions. A reinforcement frame is provided in the door panel assembly and includes a front member extending substantially along the front edge portion of the door panel assembly, a rear member extending substantially along the rear edge portion of the door panel assembly and a longitudinal member extending between the front and rear members. The longitudinal member is connected with the front member through a gusset plate rigidly so that a sideward rigidity of the door structure can be ensured.
