The object of the invention is to avoid deformation of vehicle doors by transferring the impact in the even of a front collision from the front pillar to the center pillar while properly receiving a moment by the collision. To achieve the object, a beam member (21) attached to an inner panel (15) has a part (21C) formed in S-shape in cross-section, an upper part (21D) of the S-shape part (21C) extending along a line (W) that levels with the lower boundary of the window (19), while a lower part (21E) of the S-shape part extending parallel to and lower than the line (W). The lower part (21E) further extends downward toward the front of the vehicle so that the front end of the lower part (21Ef) of the S-shape part levels with an upper door hinge (33).
