PROBLEM TO BE SOLVED: To provide a vehicle door frame structure achieving low manufacturing costs and high productivity, and having an excellent degree of freedom for setting design widths at different portions in the longitudinal direction of a frame. SOLUTION: The door frame structure includes a frame body and an exterior member. The frame body has a glass opposing part opposed to an edge portion of a door glass, a design part on the outside of a vehicle, a cylindrical part on the inside of the vehicle, and a glass guide section of recess-shaped cross section surrounded by these parts. The frame body is formed as one member being continuous from an upper sash part to a side sash part by shaping the cylindrical part in a certain cross section from the upper sash part to the side sash part, and by bending a corner part. The exterior member respectively covers the design parts of the upper sash part and the side sash part of the frame body from the outside of the vehicle. The width of the design part in the frame body varies in at least one location in the longitudinal direction. COPYRIGHT: (C)2011,JPO&INPIT
