Further, the load is transmitted from the ridge portions 30H and 30J of the hinge reinforcement 30 to the ridge portions 32D and 32E of the front pillar gusset 32, and the dash panel along the ridge portions 32D and 32E of the front pillar gusset 32. 52.

  Further, as shown in FIG. 1, a portion P1 where the ridge line portions 32D and 32E of the front pillar gusset 32 and the ridge line portion 30H and the ridge line portion 30J of the hinge reinforcement 30 face each other is a centroid Z1 of a longitudinally perpendicular cross section of the front pillar 14. More on the front side door 16 side (vehicle rear side).

  For this reason, the side hinge load F1 causes the door hinge mounting portion 20D of the pillar outer panel 20 to be twisted inward in the vehicle width direction (in the direction of arrow A, which is the counterclockwise rotation direction in FIG. 1), centered on the centroid Z1 of the longitudinal cross section. Can be suppressed by the reaction force (arrow F2 in FIG. 1) between the ridge lines 32D and 32E of the front pillar gusset 32 and the ridge lines 30H and 30J of the hinge reinforcement 30. That is, a moment in the direction opposite to the direction of arrow A can be generated.

  Therefore, in this embodiment, the cross-sectional collapse of the front pillar 14 and the twist of the front pillar 14 can be suppressed. For this reason, the side impact load input from the door hinge 18 to the front pillar 14 can be efficiently transmitted to the front pillar gusset 32 via the hinge reinforcement 30. Further, since the hinge reinforcement 30 is used, it is not necessary to provide a new reinforcing member in the closed cross section 26 of the front pillar 14, so that the increase in the number of parts can be suppressed and the weight can be reduced.

Further, in the present embodiment, the impact beam mounting portion 68B of the door inner panel 68 to which the flange 72C of the front end edge portion of the impact beam extension 72 is coupled is disposed outside the hinge reinforcement 30 in the vehicle width direction. The reinforcement 30 and the impact beam mounting portion 68B of the door inner panel 68 overlap each other in a vehicle side view (a state in which the vehicle is viewed from the vehicle width direction).

For this reason, when the impact beam 70 moves toward the inside of the vehicle width at the time of a vehicle-side collision, the load from the tip 70A of the impact beam 70 (arrow F3 in FIG. 1) is moved up and down through the impact beam extension 72. It is efficiently transmitted to the hinge reinforcement 30 and the front pillar gusset 32 without going through the transmission path in the direction.

  As a result, a high reaction force is generated by the hinge reinforcement 30 and the front pillar gusset 32, and the moment generated in the front pillar 14 can be further reduced.

  While the present invention has been described in detail with respect to specific embodiments, the present invention is not limited to the above-described embodiments, and various other embodiments are possible within the scope of the present invention. It will be apparent to those skilled in the art. For example, in the above embodiment, the box-shaped hinge reinforcement 30 is disposed as the reinforcing member, but the shape of the hinge reinforcement 30 may be a shape other than the box shape. Further, a reinforcing member other than the hinge reinforcement 30 may be arranged.

  In the above embodiment, the front pillar gusset 32 is used as the load transmission member. Alternatively, the front pillar 14 and the dash panel 52 may be connected by a load transmission member other than the front pillar gusset 32. Good.

  Moreover, in the said embodiment, although the front pillar gusset 32 was couple | bonded with the dash panel 52, it replaced with the dash panel 52, and the structure which couple | bonded the front pillar gusset 32 with other rigid members (body), such as a dash panel reinforcement.
