2. Description of the Related Art Conventionally, there is a vehicle provided with a back door which opens and closes in a vertical direction depending on the type of vehicle. Various proposals have been made for the mounting structure of the window glass of this type of back door. In a particularly general structure, a substantially rectangular frame is formed on the door panel, and a stepped portion that is recessed inside the vehicle for fitting the window glass is formed on the inner periphery of the frame. Then, the window glass is fitted so as to overlap the stepped portion on the inner periphery of the frame, and the stepped portion is fixed with a means such as an adhesive or a bolt. Also, with such a mounting structure, the outer periphery of the window glass is molded with resin, and
A structure in which the gap between the window glass and the door panel is filled with the molding is generally performed.

One of the problems with the back door that opens and closes in the vertical direction is the treatment of rainwater when it is opened. The attached rainwater flows down along the slope of the open back door surface. Therefore, when the rear end of the opened back door is positioned higher than the front end, the rainwater that flows down flows into the vehicle from between the front end of the back door and the vehicle body. As a method for solving such a problem, a structure in which a water guide piece is provided at an upper corner of a back window glass is proposed in Japanese Utility Model Publication No. 49-146618. Since the technique disclosed in Japanese Utility Model Laid-Open No. 49-146618 only opens and closes the back window glass, when it is applied to open and close the back door as described above,
A water guide piece will be provided at the upper corner of the back door.
