Abstract: A vechile body structure which increases the strength and rigidity of side roof rails, and improves sealability of a between a slide door and a vehicle body is provided. A side roof rail is composed of an outer side roof rail panel and an inner side roof rail panel. An upper rail is disposed more inwardly in the vechile body than a lower weld flange at which the outer side roof rail panel and the inner side roof rail panel are bonded together. Thus, an abrupt change in the cross section of the side roof rail can be avoided.

Abstract: A integrally formed synthetic resin lower sash for an automotive vehicle door structured so as to be disposed within a door panel and guide a window glass received within the door panel in a vertical direction. In order to reduce a frictional sound generated between a moving glass and the lower sash, the lower sash is constituted by an outer wing, an inner wing and a frame surrounding an edge portion of the window glass, a plurality of extending portions projecting toward the surface of the opposing window glasses and intermittently disposed to a direction of guiding the window glass are provided in the outer wing and the inner wing, and a projecting piece slidably in contact with each of inner and outer surfaces of the glass is extended in such a manner as to continue from the expanding portion, thereby forming a glass guide.
