PURPOSE: To secure the sealing as well as the lateral view, by projecting upward, in a door body, a sealing body.

CONSTITUTION: When the lower end of the door glass 3 is moved outwardly, and thereby the sealing lip 10b is deformed flexibly toward a base section 10a, the firm contact state is kept. Therefore the water flowing down along the surface of the door glass 3, or the water directly striking the door waist section W would not dwell on the part where the sealing lip 10b and the door glass 3 are in firm contact, so that the sealing can be complete. Further, as the sealing lip 10b is located within the door body 1, and would not project into the effective view of the door glass 3, the lateral view would not be narrowed.
