Vehicle door structure

A vehicle door structure comprising:

• a frame inner that is formed in an L shape in a cross-section orthogonal to a length direction and that configures an inner wall portion at a door thickness direction inside of a door frame and an upper wall portion at a door up-down direction upper side of the door frame;
• and
• a frame outer that is formed in an L shape in a cross-section orthogonal to the length direction, that configures an outer wall portion at the door thickness direction outside of the door frame and a lower wall portion at the door up-down direction lower side of the door frame,
• wherein a door up-down direction upper side end portion of the outer wall portion is welded to a door thickness direction outside end portion of the upper wall portion, and a door thickness direction inside end portion of the lower wall portion is welded to a door up-down direction lower side end portion of the inner wall portion, so as to configure a closed cross-section profile together with the frame inner.
