  A restricting bolt 50, which is a restricting member having a length of about ⅔ of the width of the front pillar 20, is screwed onto the nut 48 from the outside in the vehicle width direction. That is, the restriction bolt 50 is erected on the door inner panel 34 toward the inner side in the vehicle width direction. Here, the regulation bolt 50 is arranged at a position corresponding to the insertion port 14A of the instrument panel reinforcement 14 when viewed from the side in the vehicle width direction (see FIG. 1). Further, the regulation bolt 50 penetrates through the door trim 42, and its tip is inserted into the insertion opening 14A when the front side door 30 is in the closed state.

  Next, the operation of the vehicle side part structure 10 according to the first embodiment configured as described above will be described.

  When the vehicle 12 collides with a side surface, for example, when another vehicle (not shown) collides with the front side door 30 of the vehicle 12, a collision load is input from the outside in the vehicle width direction (door thickness direction).

  Here, when the collision load is input, the deformation amount of the front pillar 20 and the center pillar 16 (see FIG. 1) is smaller than that of the front side door 30. Therefore, as shown in FIG. 3, in the front side door 30, the center side in the vehicle front-rear direction is more inward in the vehicle width direction than the vehicle front side fixed to the front pillar 20 and the vehicle rear side fixed to the center pillar 16. Be drawn into. Specifically, the door outer panel 32 is largely deformed inward in the vehicle width direction, and the door inner panel 34 is also deformed inward in the vehicle width direction. Further, due to the deformation of the door hinge 38 and its peripheral portions (the portions fixed by the bolts 44A and the nuts 44B, and the portions fixed by the bolts 46A and the nuts 46B), the vehicle front portion of the front side door 30 moves toward the vehicle rear side. It shifts.

  Then, with the deformation of the front side door 30 to the inner side in the vehicle width direction and the displacement to the rear side of the vehicle, the restriction bolt 50 moves to the inner side in the vehicle width direction and the rear side of the vehicle. Here, when the regulation bolt 50 moves inward in the vehicle width direction, the threaded portion 50B of the regulation bolt 50 is deeply inserted into the instrument panel reinforcement 14 from the insertion opening 14A. When the restriction bolt 50 moves toward the vehicle rear side, the screw portion 50B comes into contact with the inner wall of the instrument panel reinforcement 14 on the vehicle rear side. That is, the restriction bolt 50 is locked to the instrument panel reinforcement 14.

  As described above, in the vehicle side portion structure 10 of the present embodiment, when the side collision occurs, the front side door 30 is deformed inward in the vehicle width direction and is displaced toward the vehicle rear side, so that the regulation bolt 50 is attached to the instrument panel reinforcement 14. Be locked. As a result, further intrusion of the front side door 30 inside the vehicle width direction is suppressed. In the present embodiment, as shown in FIG. 3, the restriction bolt 50 is locked to the instrument panel reinforcement 14, so that the head portion 50A of the restriction bolt 50 is on the vehicle rear side and the tip of the screw portion 50B is on the vehicle front side. However, the front side door 30 is prevented from further intruding inward in the vehicle width direction.

  Further, since the restriction bolt 50 is locked to the instrument panel reinforcement 14, a part of the collision load received by the front side door 30 from the outside in the vehicle width direction is transmitted from the front side door 30 to the instrument panel reinforcement 14. That is, according to the present embodiment, the collision load received by the front side door 30 from the outside in the vehicle width direction is efficiently transmitted in the axial direction of the front pillar 20 and the instrument panel reinforcement 14. The collision load transmitted in the axial direction of the instrument panel reinforcement 14 is absorbed by the instrument panel reinforcement 14 and also transmitted to and absorbed by the front pillar 20 on the opposite side.

<Second Embodiment>
Next, the vehicle side part structure 10 according to the second embodiment shown in FIG. 4 will be described. The same parts as those in the first embodiment are designated by the same reference numerals, and detailed description (including common operations) will be omitted as appropriate.

  As shown in FIG. 4, in the vehicle side part structure 10 according to the second embodiment, instead of the restriction bolt 50 of the first embodiment, a restriction plate 52 which is a substantially “L” -shaped metal plate member. Is provided as a regulating member. Specifically, the regulation plate 52 is a plate member having a width in the vehicle up-down direction, and a fixing portion 52A extending in the vehicle front-rear direction is joined to the reinforcing patch 37. The locking portion 52B extends from the side end portion toward the inside in the vehicle width direction. Here, the reinforcing patch 37 is provided with a substantially rectangular insertion opening 37A, the door inner panel 34 is provided with a substantially rectangular insertion opening 34D, and the locking portion 52B of the regulation plate 52 is provided with the insertion opening 37A, It is inserted through 34D. Further, the locking portion 52B penetrates the door trim 42. As a result, the locking portion 52B is erected on the door inner panel 34 toward the inside in the vehicle width direction.

  Here, the locking portion 52B is formed so that the width in the vehicle vertical direction is narrower than the inner diameter of the insertion port 14A of the instrument panel reinforcement 14. Further, the locking portion 52B is arranged at a position corresponding to the insertion opening 14A of the instrument panel reinforcement 14 when viewed from the side in the vehicle width direction, and when the front side door 30 is in the closed state, the front end portion has the insertion opening 14A. Has been inserted against.

  Then, also in the present embodiment, it is possible to obtain the same effect as that of the first embodiment. That is, in the vehicle side portion structure 10 of the present embodiment, at the time of a side collision, the front side door 30 is deformed inward in the vehicle width direction and is displaced toward the vehicle rear side, so that the locking portion 52B of the regulation plate 52 is formed. Is locked to the instrument panel reinforcement 14. As a result, further intrusion of the front side door 30 inside the vehicle width direction is suppressed.

  Further, since the locking portion 52B is locked to the instrument panel reinforcement 14, a part of the collision load received by the front side door 30 from the outside in the vehicle width direction is transmitted from the front side door 30 to the instrument panel reinforcement 14. That is, according to the present embodiment, the collision load received by the front side door 30 from the outside in the vehicle width direction is efficiently transmitted in the axial direction of the front pillar 20 and the instrument panel reinforcement 14. As in the first embodiment, the collision load transmitted in the axial direction of the instrument panel reinforcement 14 is absorbed by the instrument panel reinforcement 14 and also transmitted to and absorbed by the front pillar 20 on the opposite side.
