  As shown in FIG. 1, the tail gate 3 has the hinge 4 and the open stay 7 relatively close to each other, so that moment and torsional displacement are generated in the hinge 4 and the open stay 7 when the tail gate 3 is opened and closed. Even if it is added, the moment received by the tailgate 3 is small, so there is no distortion.

  As shown in FIG. 3, the tailgate 3 is rotated in the direction of arrow E to close the gate opening 2d. At this time, the gate hinge member 42 rotates in the extending direction (shear direction) of the front and back surfaces of the gate hinge member 42 and substantially coincides with the rotating direction of the tail gate 3. A force due to opening and closing is applied to the front and back surfaces of the gate hinge member 42. For this reason, the hinge 4 is strong in the opening / closing direction of the tail gate 3, the rigidity is greatly improved, and the gate hinge member 42 can be downsized.
