Since the surface portions 25 and 25 are attached to the front inner wall 3a and the rear inner wall 3b of the outer panel 3, the front pillar 10 is deformed by an impact transmitted from the upper member 2 to the front pillar 10 when the front portion of the vehicle body collides. In addition, the impact transmitted to the front pillar 10 can be transmitted to the rear door 35 via the hinge 35A.
As a result, deformation or the like hardly occurs at the hinge 35A portion, and unintentional opening of the door 35 at the time of a collision can be suitably prevented.

Further, since the door hinge stiffener 20 includes an upper surface portion 26 a and a lower surface portion 26 b provided in parallel to each other at the upper and lower ends of the side surface portion 21, the upper surface portion 26 a and the lower surface portion 26 b are arranged in front of and behind the side surface portion 21. It functions as a turn-up that increases the strength in the direction, and in the event of a collision or the like, it is possible to ensure an effective rigidity strength against a bending load along the longitudinal direction of the vehicle body.
Therefore, it becomes difficult for the front pillar 10 to be deformed due to the impact transmitted to the front pillar 10, and thereby the impact transmitted to the front pillar 10 can be transmitted to the rear door 35 side via the hinge 35A.

Also, the end of the upper surface portion 26a is folded upward to form the upper surface portion 26a in an L shape, and the end portion of the lower surface portion 26b is folded downward to form the lower surface portion 26b in an L shape. Since the flange portions 26a 'and 26b' are formed, in the event of a collision or the like, it is possible to ensure more effective rigidity and strength against a bending load along the longitudinal direction of the vehicle body, and in the longitudinal direction of the vehicle body. The amount of load transmission can be increased.
Further, the load can be sufficiently transmitted in the front-rear direction of the vehicle body without being affected by the shape of the side surface portion 21 of the door hinge stiffener 20.

  Further, since the door hinge stiffener 20 is configured by joining the second member 20B to the first member 20A, molding corresponding to the shape of the outer panel 3 of the front pillar 10 is easily performed. As a result, even when the inner side surface of the outer panel 3 has an uneven surface or an inclined surface, the side surface portion 21 of the door hinge stiffener 20 can be brought into close contact with the inner side surface of the outer panel 3. Can be increased.

  Further, the door hinge stiffener 20 is mounted on the outer panel 3 and the upper surface portion 26a and the lower surface portion 26b are arranged in a horizontal state. Therefore, an impact transmitted from the upper member 2 to the front pillar 10 is transmitted via the hinge 35A. Good transmission to the rear door 35 side is possible.

  Further, the door hinge stiffener 20 is located between the upper member 2 disposed in front of the vehicle body and the door beam 39 provided on the door 35 in a state of being attached to the outer panel 3, so that the upper member 2 and the door hinge stiffener 20 are located. And the door beam 39 are arranged in a straight line, and the impact at the time of collision is directly input to the door hinge stiffener 20 through the upper member 2 arranged in front of the vehicle body, and from the door hinge stiffener 20 to the hinge 35A. To the rear door 35 side. Therefore, the impact at the time of collision is satisfactorily transmitted from the upper member 2 to the door beam 39 via the door hinge stiffener 20, and load transmission in the longitudinal direction of the vehicle body is smoothly performed.

  In addition, since the plurality of bulkheads 40 are arranged in the front pillar 10 below the door hinge stiffener 20 and spaced apart in the vertical direction, the front pillar 10 is secured while ensuring effective rigidity and strength by the door hinge stiffener 20. A space can be formed in the interior, and weight reduction can be achieved while increasing the strength of the front pillar 10.
