PROBLEM TO BE SOLVED: To provide an automotive door structure that improves safety and deliverability of an occupant by making a side door deform in accordance with the preset deformation amount of the side door with respect to an impact applied to the front side of a vehicle. SOLUTION: This door structure is provided with a vulnerable portion and a protruding portion. The vulnerable portion is disposed to the cabin wall side from a window frame bottom line 36 of a front portion of a side door 3 mounted on a vehicle body, so that it protrudes toward vehicle inside wall. The protrusion portion is disposed in a rear portion of the side door 3, so that it protrudes toward vehicle outside wall. Alternatively, the door structure may be configured with a flexed reinforcement member 37 that is connected with the cabin wall at several points generally at the height which is in the vicinity of the window frame bottom line 36 of the side door 3. The door structure may also be provided with a reinforcement member 39 that runs along a wheel arch 3a on the bottom line of the side door 3 and is disposed on the cabin wall, and a notch 3b inclined upwardly so that a rear end lower portion of the side door 3 does not contact a vehicle component member adjacent to the side door 3.
