Description

  The present invention relates to a vehicle door structure including a partition glass fixed to a door.

  Some rear doors of a vehicle adopt a structure in which partition glass is fitted and fixed to a window portion defined by a center sash of a window frame constituted by an inner panel and an outer panel.

  By the way, the rear door is configured as a closed cross-sectional structure in which the inner periphery of the window frame is opened and the outer periphery of the door is closed by an inner panel and an outer panel, which are press-formed products of sheet metal. The partition glass is supported by one reinforcement through a soft resin or rubber weather strip. Specifically, as shown in the partial perspective view of FIG. 9, a partition support 120 made of sheet metal that is bent and formed in a step shape is welded to the upper end edge of the reinforcement 110, and the partition support 120 is not used for this purpose. A structure for receiving the lower portion of the illustrated weather strip is employed.

  Alternatively, as proposed in Patent Document 1, a lip extending from the indoor side upper end of the weather strip to the interior trim side is formed together with a support structure by a glass holding panel (glass receiving part) corresponding to the partition support. In addition, a structure is employed in which a protrusion that protrudes from the weather strip toward the inner panel is formed below the lip, and the weather strip is supported on the inner panel by placing the protrusion on the upper edge of the inner panel.
