Abstract: A vehicle door frame includes a sash frame that forms a vehicle door frame body and a bracket joined to the sash frame, wherein the sash frame and the bracket are made to mutually overlap each other so that an edge portion of one of the sash frame and the bracket is positioned on the other of the sash frame and the bracket. The sash frame and the bracket are fixed to each other at the edge portion by welding, thereby forming a welded portion thereat. The sash frame and the bracket are fixed to each other by an adhesive injected in between opposed surfaces of the mutually overlapping portions of the sash frame and the bracket, thereby forming an adhesion portion thereat. A method of producing such a vehicle door frame is also disclosed.

Abstract: A vehicle door sash having a uniform cross-sectional shape is provided, including an enclosed section on a vehicle inner side, and an outer extending wall which extends from the enclosed section toward the vehicle outer side, the enclosed section provided with inner and outer walls, with respect to a vehicle width direction, a body-side wall, and an adjacent-to-glass wall that is adjacent to a window glass of the vehicle door. A weather strip is abutted against the body-side of the outer extending wall, and a glass runner is abutted against the window side of the outer extending wall. The body-side wall of the enclosed section is straight in cross section. A thickness of at least one of the inner and outer walls of the enclosed section is greater than a thickness of each of the body-side wall and the adjacent-to-glass wall.
