STRUCTURE FOR VEHICLE DOOR FRAME AND METHOD FOR MANUFACTURING VEHICLE DOOR FRAME

摘要

A door frame wherein a frame body includes: a facing section which faces glass, the facing section facing an edge of door glass; a design section which is located on the exterior side of the vehicle; a tubular section which is located on the interior side of the vehicle; and a glass guide section which is surrounded by the facing section, the design section on the exterior side of the vehicle, and the tubular section and has a recessed cross-section, the frame body being formed as a single member which is continuous from an upper sash section to a side sash section, and being configured in such a manner that the tubular section has a constant cross-section from the upper sash section to the side sash section and that a corner section is bent. At least a portion of the design section of the frame body in the longitudinal direction thereof is adapted to have a width which is different from that of the remaining portion, and the design section is covered by the exterior member from the exterior side of the vehicle. The configuration increases productivity while reducing manufacturing cost and increases the degree of freedom of setting design widths at different portions in the longitudinal direction of the frame.
