VEHICLE DOOR STRUCTURE

PROBLEM TO BE SOLVED: To provide a vehicle door structure in which a load of a front collision can be transmitted to the rear side effectively, collision bearing force can be increased, and a single impact bar can respond to both of a front collision and a side collision.SOLUTION: At the front edge of an impact bar 16, a vertical surface part 16A which is positioned inside in a vehicular width direction and extends vertically, and upper and lower lateral surface parts 16B, 16C which extend from both of the upper and lower edges of the vertical surface part to the outside in the vehicular width direction form a U-shaped part 17, and the impact bar 16 is jointed to a surface 3e in the vehicular width direction of a door inner panel 3 by first jointing parts 16D, 16E which extend vertically from the front edges of the upper and lower lateral surface parts 16B, 16C, respectively. Further, upper and lower outer surface parts 16F, 16G which extend vertically from outer edges of the upper and lower lateral surface parts 16B, 16C are provided, and the impact bar 16 is jointed to a surface 3f in the back and forth direction of the door inner panel 3 by second jointing parts 16H, 16J which extend from the front edges of the outer surface parts 16F, 16G to the vehicular front side, respectively.
