PROBLEM TO BE SOLVED: To provide a door structure for a vehicle capable of suppressing the permanent deformation of a door. SOLUTION: A pair of front and rear coupling parts 48, 50 of a hinge side panel 18 with a belt line reinforcing member 40 forms a so-called truss-shape 52 with a coupling part 46 of a frame bracket 24 with the belt line reinforcing member 40. Therefore, even when the rotational moment (shown by an arrow M1) is applied to the hinge side panel 18 associated with the thermal expansion force (shown by an arrow F1) generated in a door outer panel 14, the rotational moment (shown by the arrow M1) can be reliably transmitted to the belt line reinforcing member 40 formed of a material having the coefficient of linear expansion smaller than that of the door outer panel 14, such as steel via the coupling part 46 having the truss shape 52 and the pair of front and rear coupling parts 48, 50. Thus, the rotational deformation of the hinge side panel 18 associated with the thermal expansion of the door outer panel 14 can be received and suppressed by the belt line reinforcing member 40.
