Abstract
A vehicle door structure for suppressing permanent deformation due to thermal distortion of a door is described. A door inner paneland a door outer panelare configured in aluminum alloy or the like. An impact beamand a belt line inner reinforcementare joined to the door inner panel. The impact beamand the belt line inner reinforcementare configured from a material, such as steel, with a smaller linear expansion coefficient than the door outer panel. Therefore, even if the dooras a whole is, for example, placed in a high temperature environment such as a bake oven in electrophoretic coating, the door inner panelside and the door outer panelside are restrained, respectively, by the belt line inner reinforcementand the impact beam. Thus, permanent deformation due to thermal distortion at the door outer panelside, due to a difference in the thermal expansion conditions of the door inner panelside and the door outer panelside, may be suppressed.
