Specifically, the distance in the horizontal direction between the top of the concave portion on the uneven portion and the flat surface is set to L. Therefore, a gap of size L is formed between the uneven portion and the door inner panel, and the flat surface is adhered to the flat surface portion of the door inner panel in close contact.

To sum up, the sealing structure of the frameless vehicle door of the present invention forms at least two sealing cavities through the sealing lip and the side window glass to provide better sealing and sound insulation functions. The sealing structure of the frameless vehicle door in the present invention does not require additional guide grooves, and when the vehicle door is closed, the side window glass sealing strip and the trim panel are in a flush state, and the vehicle door is more beautiful when the vehicle door is closed.
