  However, in the vehicle door disclosed in Patent Document 1, since the peripheral portion of the plate glass is supported in a state where it enters the channel portion of the sash, the portion of the sash outside the vehicle is located outside the vehicle rather than the surface of the plate glass. It will project toward and a level difference will occur between the sash and the plate glass. If there is a step, it will be difficult to reduce wind noise and air resistance during travel, and it will have to be an external design that assumes that there is a step.

  Further, since the plate glass is heavy, if the window is made of plate glass as in the vehicle door of Patent Document 1, high strength is required for the portion to which the plate glass is attached, making it difficult to reduce the weight of the door body, and consequently the door becomes heavy. End up.

  The present invention has been made in view of such a point, and an object of the present invention is to reduce wind noise and air resistance in a vehicle door with a sash to reduce wind noise and air resistance, and to allow freedom of external design.
