As shown in FIG. 5, the deformation prevention bracket 60 includes a horizontal portion 62 extending in the vehicle front-rear direction and a vertical portion 64 extending in the vehicle upward direction so as to be perpendicular to the vehicle rear end of the horizontal portion 62. Has been. That is, the deformation preventing bracket 60 has an L-shaped cross section when viewed in the vehicle inside / outside direction.

  Specifically, the horizontal portion 62 is formed with one end surface 62a extending in the vehicle upward direction from the vehicle outer end and the other end surface 62b extending in the vehicle downward direction from the vehicle inner end. On the other hand, the vertical portion 64 is formed with one end surface 64a extending in the vehicle front direction from the vehicle outer end and the other end surface 64b extending from the vehicle inner end to the vehicle rear side. The horizontal portion 62 and the vertical portion 64 have protrusions 62c and 64c that extend inward and outward of the vehicle in order to improve rigidity. The horizontal portion 62 protrudes toward the vehicle lower side and the vertical portion 64 protrudes toward the vehicle rear side. Two places are formed respectively.

  The deformation preventing bracket 60 is fixed by welding the end portions 62 a and 64 a of the horizontal portion 62 and the vertical portion 64 in contact with the vehicle inner surface of the handle support bracket 56. One end surface 62 a of the horizontal portion 62 is in contact with the inner surface 54 b of the handle support bracket 56, and one end surface 64 a of the vertical portion 64 is in contact with the vehicle inner surface of the peripheral edge portion 54 a of the handle support bracket 56. That is, the one end surface 62a of the horizontal portion 62 and the one end surface 64a of the vertical portion 64 are formed in accordance with the shape of the handle support bracket.

The predetermined interval is closer than the interval between the outside handle 10 and the handle support bracket 56 and the inner panel 70.
The operation of the thus configured vehicle door according to the present invention will be described below.

When the vehicle 1 is in a normal state, the other end surfaces 62b and 64b of the deformation preventing bracket 60 are provided with a sufficient distance from the inner panel 70. Absent.
For this reason, the deformation preventing bracket can be molded relatively easily without requiring a high degree of accuracy in molding, and can be easily mounted.

On the other hand, for example, when the vehicle 1 collides with the side, the rear door 2 is deformed from the center side where the rigidity is relatively low, and the outside handle 10 provided on the outer panel 50 of the rear door 2 Move to.
When the vehicle rear side lower portion of the outside handle 10 moves by a predetermined amount or more, the other end surfaces 62b and 64b of the deformation prevention bracket 60 provided on the vehicle rear side lower portion come into contact with the inner panel 70.

  Here, the deformation preventing bracket 60 has an L-shape composed of a horizontal portion 62 and a vertical portion 64, and the horizontal portion 62 and the vertical portion 64 are formed with protrusions 62c and 64c. It has sufficient rigidity in the direction. The deformation preventing bracket 60 is such that the horizontal portion 62 and the vertical portion 64 are both parallel to the inner panel 70 and have a predetermined interval, so that when the outside handle 10 is moved, the other end surfaces 62b and 64b are substantially the same. At the same time, the contact with the inner panel 70 ensures a sufficient contact area.

Therefore, the movement of the outside handle 10 to the vehicle inner side is reliably restricted by contacting the inner panel 70 of the deformation preventing bracket 60.
In FIG. 3, the latch mechanisms 4 and 6 are released by pulling the link rod 14 downward (front side of the vehicle), but the outside handle 10 is rotated counterclockwise in a top view due to a side collision. By doing so, it is considered that the link rod 14 is pulled downward in the drawing and the latch mechanisms 4 and 6 are released. However, the rotation of the outside handle 10 is suppressed by disposing the deformation preventing bracket 60 on the side opposite to the moving direction of the link rod 14 that releases the latch mechanisms 4 and 6 with respect to the outside handle 10. The release of the latch mechanisms 4 and 6 can also be suppressed.

  From the above, by providing the deformation prevention bracket 60 in the outside handle mounting portion 52, when the outside handle 10 moves to the inside of the vehicle due to deformation of the rear door 2 due to a side collision or the like, the deformation prevention bracket 60 Since the other end surfaces 62b and 64b come into contact with the inner panel 70 to restrict the movement, the movement of the link rod 14 connected to the outside handle can be suppressed to a slight amount, and the latch mechanisms 4 and 6 The fully closed state of the rear door 2 can be reliably held without being released.
