Abstract

The utility model relates to the technical field of vehicle bodies, and provides a vehicle door sealing device, a vehicle door and a vehicle. The vehicle door sealing device comprises a glass trough capable of being installed on a vehicle door, a trough body allowing the vehicle door glass to be embedded is formed in the side, facing the vehicle door glass, of the glass trough, a first lip edge abutting against the vehicle door glass is arranged on the inner side wall of the trough body, and the upper portion of the first lip edge is vertically arranged in the vertical direction of a whole vehicle. According to the vehicle door sealing device, the upper portion of the first lip edge is limited to be vertically arranged in the vertical direction of the whole vehicle, so that the step difference between the upper portion of the first lip edge and the vehicle window glass is small, water leakage of the upper portion of a sealing trough of the vehicle can be well prevented, and the sealing performance of the glass trough is improved.
