2. Description of the Related Art As a vehicle door of this type, there is known a door window glass that is lifted up and down so as to open and close between a door outer panel and a door inner panel. A glass channel is usually provided at the lower end of the door window glass, and a window glass elevating device provided between the door outer panel and the door inner panel is configured to elevate the door window glass through the glass channel.

A weather strip having a recessed portion is attached to the periphery of the door window except the lower edge of the door window where the door window glass appears and disappears, facing the peripheral edge of the door window glass. The weather strip is a sand that is generated when water penetrates in rainy weather or when the vehicle is traveling, because the peripheral edge of the door window glass intrudes into the concave portion of the weather strip and adheres to the weather strip at least when the door window glass closes the door window. Prevents dust from entering the vehicle interior. Therefore, it is preferable that the concave portion of the weather strip is formed as narrow as possible so as to be in close contact with the peripheral edge of the door window glass.

However, there is a problem in that the driving force of the window glass lifting device must be increased. In order to eliminate such a problem, if the recess of the weather strip is formed with a margin with respect to the thickness of the door window glass, the weather strip will play inside the recess, and There is a risk that the window glass will no longer be in close contact with the periphery of the window glass, and abnormal noise will occur due to rattling of the door window glass, and that not only water in rainy weather, but also drafts, dust, and the like when the vehicle is running will enter the vehicle interior.

An object of the present invention is to increase the frictional resistance of the window glass when moving up and down, to smoothly move the window glass up and down without increasing the operating force of the window glass lifting device and the load of the motor, and the door window. It is an object of the present invention to provide a vehicle door window structure capable of improving the adhesion between the weather strip and the door window glass when the glass is closed. Another object of the present invention is to improve the adhesion between the weather strip and the door window glass when the door window glass is closed to reduce wind noise while the vehicle is running, and to improve the appearance of the vehicle door. To provide a window structure.
