To improve vibration damping effect of an outer panel by a damping member to inhibit noise transmitted from a door to a vehicle cabin as much as possible.SOLUTION: A vehicle door structure includes: an inner panel 5; an outer panel 4 including a hem part 10 connecting a peripheral edge part of the inner panel 5 by swaging; and rigid members 14, 15, 21 (11A) disposed between the inner panel 5 and the outer panel 4. The vehicle door structure includes a damping member 22 which is disposed between the outer panel 4 and the rigid members 14, 15, 21 (11A) so as to contact with these members. The damping member 22 is disposed at a portion located adjacent to the hem part 10.SELECTED DRAWING: Figure 1 【課題】減衰部材によるアウタパネルの振動減衰効果を高めることで、ドアから車室内へ伝達されるノイズを可及的に抑制すること。【解決手段】インナパネル５と、該インナパネル５の周縁部をカシメ接続するヘム部１０を備えるアウタパネル４と、インナパネル５およびアウタパネル４の間に配設される剛性部材１４，１５，２１（，１１Ａ）とを備え、アウタパネル４および剛性部材１４，１５，２１（，１１Ａ）に当接するように、これらの間に介在する減衰部材２２を備え、減衰部材２２は、ヘム部１０に隣接する部位に配設された。【選択図】図１
