PROBLEM TO BE SOLVED: To provide a front door structure capable of transmitting a collision load upon head-on collision to a pillar-less reinforcing member and vertically distributing the load, and capable of vertically distributing a collision load upon side collision.SOLUTION: A reinforcing member 6 comprises, in a transverse sectional plan view, a base surface 6a facing outward in the vehicle width direction and a front vertical wall surface 6b continuous from the front edge of the base surface 6a and inwardly folded in the vehicle width direction and facing the front side of the vehicle. An extension plate (extension part) 10 is arranged on the rear end part of a belt line reinforcing member 9. The extension plate 10 comprises a transmitting part 10a transmitting a load from the belt line reinforcing member 9 to the pillar-less reinforcing member 6, and an upper extension part 10b and a lower extension part 10c continuous from the transmitting part 10a and extending in the vertical direction and being fixed to the pillar-less reinforcing member 6, and has an approximately T-shape in a side view. The transmitting part 10a comprises a rear vertical wall surface 10d in contact with the front vertical wall surface 6b of the pillar-less reinforcing member 6. |
