VEHICLE DOOR STRUCTURE

A vehicle door structure includes a door sash part and a sash retainer. A paint sealer is applied to a periphery of a vehicle lower side of the sash retainer continuously without a gap from an inner side to an outer side in a vehicle width direction through a vehicle lower portion so as to close a space between the sash retainer and the door sash part. The door sash part has a region that is lower than an application upper end of the paint sealer, that has both sides in the vehicle width direction and a vehicle lower side that are surrounded by the paint sealer, that is disposed in surface-to-surface contact with the sash retainer. A drain hole configured to drain liquid is provided on the region.
