  The present invention relates to a vehicle door structure provided with a partition sash that partitions a window opening at the upper part of the door into an elevating glass part and a fixed glass part, and more particularly to a structure for fixing the partition sash to an inner panel. is there.

  In general, a door panel constituting a vehicle door has a hollow structure in which a door outer panel and a door inner panel are joined at a peripheral portion, and a partition sash that partitions a window opening at the top of the door into a lift glass portion and a fixed glass portion. The lower end of the door is fixed to the door inner panel or the reinforcement through a bracket inside the door panel (see Patent Document 1).

  Such a door is assembled by inserting the elevating glass through the window opening and then assembling the fixed glass and the partition sash in a state where the elevating glass is lowered into the door panel. However, even before the fixed glass and partition sash were assembled, the work of inserting and assembling the elevating glass into the door panel through the window openings having substantially the same shape on the remaining three sides took time.

  Further, in Patent Document 1, the fixed part of the partition sash is largely offset rearward and separated downward from the window opening (belt line). In order to ensure rigidity, it is preferable that the fixed portion of the partition sash is disposed near the fixed glass portion and the amount of protrusion of the fixed bracket is small.

  Therefore, there is a case where a notch portion is provided at the edge of the partition sash on the fixed glass portion side, and a fixing bracket is disposed near the center of the partition sash. However, when such a fixed part is arranged near the fixed glass, it has been transmitted from the joint part at the upper end of the fixed glass to the outside of the weather strip along with a decrease in sealing performance due to aging deterioration of the weather strip that seals the periphery of the fixed glass. There is a possibility that water may enter the indoor side from the notch of the partition sash through the fixed bracket.
