Claim 0:
1. A vehicle door frame comprising:
a pillar having
a first abutting surface being located at an upper corner of a vehicle door, and
a first outer surface facing outward in a lateral direction of a vehicle;

an upper frame having
a second abutting surface being located at the corner and abutting against the first abutting surface,
a second outer surface facing outward in the lateral direction of the vehicle, being adjacent to the first outer surface, and being a flat surface or an outwardly curved surface in the lateral direction of the vehicle,
an upper end surface being an upwardly curved surface smaller in radius of curvature than the second outer surface, and forming an upper edge of the upper frame,
a lower end surface being a downwardly curved surface smaller in radius of curvature than the second outer surface, and forming a lower edge of the upper frame,
an upper boundary between the second outer surface and the upper end surface, and
a lower boundary between the second outer surface and the lower end surface;

a frame molding extending along the upper frame to cover an outside of the upper frame in the lateral direction of the vehicle, and having an inner surface facing the first outer surface and the second outer surface with a gap;
a welded part being located at a boundary between the first outer surface and the second outer surface, extending along the first abutting surface and the second abutting surface, facing the inner surface of the frame molding, and bonding the pillar and the upper frame together; and
an end cap including:
a lid that covers an end of the frame molding, and
an intervenient part being interposed between at least one of the first outer surface and the second outer surface and the inner surface of the frame molding, wherein

the welded part has a weld bead and at least one of an upper end and a lower end,
the upper end being spaced downward from the upper edge and located at or below the upper boundary,
the lower end being spaced upward from the lower edge and located at or above the lower boundary,

the upper frame includes a closed cross section, a bridging wall, and an upright wall,
the bridging wall adjoins an outside of the closed cross section in the lateral direction of the vehicle,
the upright wall adjoins an outside of the bridging wall in the lateral direction of the vehicle,
the second outer surface is an outer surface of the upright wall in the lateral direction of the vehicle,
the upright wall extends vertically and in a longitudinal direction of the upper frame,
the upper frame includes a hook that catches a weather strip, the hook projecting inward in the lateral direction of the vehicle from the upright wall, the hook located below the upper edge of the upright wall,
the upright wall includes a sealing surface for sealing a gap between the weather strip and the upright wall, the sealing surface being above the upper surface of the hook and below the upper boundary,
the weld bead projects outward in the lateral direction of the vehicle,
the gap between the frame molding and the upper frame decreases as going upward,
the intervenient part has a plate-like shape, extends frontward from the lid along a bottom edge of the frame molding between the first outer surface and the inner surface of the frame molding, and covers the lower end of the welded part,
the end cap is provided with a cutout above the intervenient part, the upper end of the welded part being exposed to outside of the intervenient part through the cutout so that the inner surface of the frame molding faces the upper end of the welded part through the cutout.
