  In the side structure of the automobile configured as described above, a side collision load indicated by an arrow X in FIG. 5 is input to the door 13 at the time of a side collision in which another vehicle collides with the side surface of the own vehicle. The door 13 tries to turn from the normal closed position to the vehicle interior side with the hinge pin 26 as the rotation center. In this case, the restricting portion 27b of the bolt member 27 provided on the facing surface portion 6c of the hinge pillar 5 described above is used. Further, it is possible to restrict the further rotation of the door 13 by abutting against the facing surface portion 15b of the door inner panel 15 whose rigidity is enhanced by the reinforcement 34.

  Further, since the impact bars 19 and 20 are pressed toward the vehicle interior side when the side impact load is input, the door 13 is indicated by an arrow Y in FIG. 5 by the force acting on the impact bars 19 and 20. In this case, the engagement portion 27d provided at the front end of the bolt member 27 in the vehicle width direction is connected to the opening hole 15b of the door inner panel 15 and the reinforcement 34. Since it engages with the hole edge of the opening hole 34a, the door 13 can be prevented from being pulled into the center pillar side.

  As described above, in the side part structure of the automobile according to the embodiment shown in FIGS. 1 to 6, the door 13 including the door outer panel 14, the door inner panel 15, and the impact bar 19 includes the hinge pillar via the hinge 21. 5 is a side structure of an automobile that is mounted on the door 5 and is erected from a hinge pillar portion (refer to the facing surface portion 6c) facing the door inner panel 15 toward the door inner panel 15, and is closed to a normal door 13 (see FIG. 5 is provided with a restricting member (see bolt member 27) for restricting the rotation of the door 13 toward the vehicle interior side at the time of a side collision (see FIG. 5).

According to this configuration, when the door 13 tries to turn from the closed position to the vehicle interior side around the hinge pin 26 of the hinge 21 at the time of a side collision of the vehicle, the restriction provided on the hinge pillar portion (see the facing surface portion 6c). Since the member (bolt member 27) abuts on the door inner panel 15 and restricts further rotation of the door 13, the rotation of the door 13 toward the vehicle interior during a side collision can be suppressed.
As a result, energy absorption (absorption of side impact load) due to deformation of the impact bars 19 and 20 can be promoted, and the amount of the door 13 entering the vehicle interior side can be suppressed.

  In addition, an opening hole 15c is formed in the door inner panel portion (see the facing surface portion 15b of the door inner panel 15) facing the restriction member (see the bolt member 27), and the tip (vehicle) of the restriction member (bolt member 27) is formed. An engagement portion 27d that engages with the opening hole 15c when the door 13 moves to the center pillar 11 side when the door 13 moves to the center pillar 11 side is provided at the front end in the width direction (FIG. 2). FIG. 5).

  According to this configuration, the impact bars 19 and 20 are pressed toward the vehicle interior via the door outer panel 14 at the time of a side collision of the vehicle, and the door 13 is pulled toward the center pillar 11 by the force acting on the impact bars 19 and 20. In this case, however, the engaging portion 27d provided at the tip of the restricting member (bolt member 27) engages with the opening hole 15c of the door inner panel 15, and the door 13 is pulled toward the center pillar 11 side. Therefore, the movement of the door 13 toward the center pillar 11 can be prevented.

  Further, the instrument panel member 30 is mounted between the left and right hinge pillars 5 and 5 via the mounting bracket 31, and the restriction member (see the bolt member 27) is connected to the mounting bracket 31 (FIG. 5).

  According to this configuration, since the above-described restricting member (bolt member 27) is connected to the instrument panel member 30 extending in the vehicle width direction via the mounting bracket 31, the side collision load input from the door 13 at the time of a side collision. It can be received not only by the hinge pillar 5 but also by the instrument panel member 30, whereby the amount of the door 13 entering the vehicle interior side can be further suppressed. Further, this configuration is established even if the collar 32 is present between the hinge pillar outer 6 and the hinge pillar inner 7.

  In addition, the mounting bracket 31 of the instrument panel member 30 is fastened to the hinge pillar 5 by a bolt (see the bolt member 27) inserted into the collar 32 provided in the hinge pillar 5 from the outside of the vehicle. A member (refer to the bolt member 27) is inserted into the collar 32 from the outside of the vehicle and is constituted by a bolt-shaped member that mounts the mounting bracket 31 to the hinge pillar 5 (see FIG. 5).

  According to this configuration, the restricting member attaches the mounting bracket 31 of the instrument panel member 30 to the hinge pillar 5 while suppressing the rotation of the door 13 toward the vehicle interior side at the time of a side collision by the restricting member (see the bolt member 27). Since the bolt-shaped member is used, it is possible to improve the mounting rigidity of the instrument panel member 30 with respect to the hinge pillar 5, and the bolt-shaped member (see the bolt member 27) is used to fasten the mounting bracket 31 and the door 13. It can also serve as both actions for suppressing the amount of intrusion into the vehicle interior side.

  In addition, the outer end is joined to the mounting portion 19a of the impact bar 19, and the inner end continuously extends to the door inner panel 15 facing the restriction member (see the bolt member 27). (See FIG. 5).

According to this configuration, the rigidity of the door inner panel 15 opposed to the regulating member (bolt member 27) can be increased by the reinforcement 34 while the impact bar 19 is disposed on the outer side inside the door 13. When the side collision occurs, the restricting member (bolt member 27) comes into contact with a portion having high door rigidity, and the rotation of the door 13 toward the vehicle interior side can be reliably suppressed.
Further, a closed section 35 is formed between the reinforcement 34 and the front surface portion 15a of the door inner panel 15 (see FIG. 5).

  According to this configuration, the closed section 35 can improve the rigidity of the door 13 in the vehicle width direction. That is, it is possible to increase the rigidity of the door with which the restricting member (see the bolt member 27) abuts at the time of a side collision.

  In addition, the restriction member (see the bolt member 27) is a restriction portion that restricts the rotation of the door 13 toward the vehicle interior side at a portion (see the facing surface portion 6c) facing the door inner panel 15 of the hinge pillar outer 6. 27b, and the outer dimension of the restricting portion 27b is larger than the diameter of the opening hole 15c (see FIG. 5).

  According to this configuration, since the outer dimension of the restricting portion 27b is formed larger than the hole diameter of the opening hole 15c, the restricting portion 27b is surely attached to the edge of the opening hole 15c of the door inner panel 15 at the time of a side collision. It can contact | abut and can suppress the rotation to the vehicle interior side of the door 13 reliably.

  FIG. 7 shows another embodiment of the side part structure of the automobile. The hexagonal heads 28b and 29b of the other two bolt members 28 and 29 positioned above and below the bolt member 27 as a regulating member are connected to the bolt member 27.
