Therefore, it is possible to make it easier to remove the rust preventive coating liquid by the second separation portion 25. In addition, the rigidity in the vertical direction of the first reinforcing member 20 and thus the tailgate body 11 can be improved. And since the 1st separation part 23 is shorter than the 2nd separation part 25, the space in the up-and-down direction of the 1st separation part 23 can be secured, and attachment of parts, such as the above-mentioned latch mechanism and predetermined wire harness, is therefore possible. Space for can be secured.

  The tailgate 10 extends in the vertical direction substantially parallel to the second spacing portion 25 and is formed on the first reinforcing member 20. The first reinforcing member 20 has substantially the same length in the vertical direction as the second spacing portion 25. The step part 26 which is a level difference is provided. Therefore, the tailgate 10 can make it easier to remove the rust preventive coating liquid by the step portion 26. Further, since the step portion 26 is substantially parallel to the second separation portion 25 and has substantially the same length, it is possible to improve the vertical rigidity of the first reinforcing member 20 and thus the tailgate body 11.

  The tailgate 10 includes a bead 27 that is formed on the first reinforcing member 20 with the vehicle width direction as a longitudinal direction and is connected to the first separation portion 23. Therefore, the bead 27 can increase the rigidity of the first reinforcing member 20 in the vehicle width direction. Further, since the bead 27 is connected to the first separation portion 23, the rust preventive coating liquid that has entered the bead 27 can be allowed to flow to the first separation portion 23.

  In this case, the bead 27 is formed at a height different from that of the first opening 24 in the vertical direction. Therefore, the 1st reinforcement member 20 can improve the rigidity of a vehicle width direction with a bead. Moreover, since the bead 27 and the 1st opening part 24 differ in the height of an up-down direction, the fall of the rigidity of the 1st reinforcement member 20 by formation of the 1st opening part 24 can be suppressed.

  The tailgate 10 is provided at a position corresponding to the first recess 12a of the first reinforcing member 20 with the longitudinal direction as the vehicle width direction. The tailgate body 11 has a concave shape on the vehicle outer side and a convex shape on the vehicle inner side. Thus, a second recess 21 having a larger degree of recess than the first recess 12a is provided. Therefore, since the degree of the dent is greater in the second recess 21 than in the first recess 12a, a gap 40 can be formed between them, and the anticorrosive coating liquid can be discharged from the gap.

  The tailgate 10 is provided with a second opening 31 for latching the tailgate body 11 to the vehicle body when the tailgate body 11 is closed, and is provided separately from the first reinforcing member 20. A second reinforcing member 30 joined to the member 20 is provided. Therefore, since the 2nd reinforcement member 30 is joined to the 1st reinforcement member 20, the rigidity of the 2nd reinforcement member 20, and by extension, the tailgate main body 11 can be improved.

A pair of tabs 28 are formed at the upper end of the substrate portion 22a, and a round hole 28a is formed in each tab. The tabs 28 and the round holes 28 a are used for positioning when the first reinforcing member 20 is attached to the inner panel 13.
Further, the round holes 29a formed at the left and right positions in the middle of the upper and lower beads 27 and the round holes 29b formed at the left and right positions below the lower beads 27 are air vent holes, respectively. That is, it is an air hole for preventing the drop of the rust preventive coating liquid from being lowered by forming the beads 27 on the upper and lower sides.
