Abstract: The present invention is constructed so that, in a structure for fitting a door molding which is provided for covering a gap between a door outer panel and a window glass, the door molding is fitted on an upper portion of the door outer panel by a thermosetting structural adhesive material. The door molding can be simply fitted on the door outer panel only by heating the thermosetting structural adhesive material. Moreover, after fitting, a firm fitting state can be maintained by the thermosetting structural adhesive material.
