The frontal crash load is transmitted from a front pillar to a center pillar in a reliable manner so that a bending moment caused by the frontal crash load is favorably supported, and the deformation of the door is avoided. A beam member attached to an inner panel includes a S shaped cross section member. An upper channel section of the S shaped cross section member extends along the lower edge of a window opening, and a lower channel section extends adjacent to and in parallel to the lower edge of a window opening in a rear part of the door and is offset toward a lower part of the vehicle body in a rear part of the door, with a front end being located at a same elevation as an upper door hinge.

Vehicle door structure

In a vehicle door structure, a beam member () having a S-shaped cross section and extending in a fore-and-aft direction of a vehicle body is attached to an inner panel (), and the upper edge of the inner panel () is formed by the beam member (). Thereby, a crash load of a frontal crash is transmitted in a favorable manner, and energy of a side impact is adequately absorbed without incurring a cost increase or a weight increase owing to the use of the door beam.
