The rear gate can be flipped up to open the rear opening of the vehicle even in places where there is little space.
Furthermore, since the tip of the second door is vertically movably connected to the edge of the rear opening of the vehicle, the first door is moved upward from the state where the rear opening is closed. By moving, the second door portion is automatically moved so as to be folded. Therefore, it is possible to realize interlocking of raising and folding of the rear gate with a simple structure.

As another aspect, it is preferable to provide a support means for supporting the first door portion with respect to the vehicle body and swinging the first door portion downward.
Thus, the second door portion can be supported together by supporting the first door portion by the support means.
In another aspect, the connection means may switch connection and disconnection between the edge of the rear opening and the second door.

As a result, by separating the edge of the rear opening and the second door, the second door can be swung regardless of the flip-up of the first door.
As another aspect, it is preferable to provide a fixing means for fixing the first door portion and the second door portion in a state of being swung so as to extend linearly.
As a result, after the edge of the rear opening of the vehicle body and the second door are separated by the connecting means, the first door and the second door are formed in a straight line by raising the rear gate. The rear gate can be flipped up while extending to the rear.

  As another aspect, the connecting means connects the edge of the rear opening of the vehicle body with the second door and the fixing of the first door and the second door by the fixing means. And the connection means for separating the edge of the rear opening of the vehicle body from the second door part and the fixing means for the first door part and the second door part. And a second state in which it is fixed in a state of being rocked so as to extend in a straight line.

  Thus, by switching the switching means to the first state, when the rear gate is flipped up, it is possible to fold the first door portion and the second door portion. Further, by switching the switching means to the first state, the rear gate can be flipped up in a state in which the first door portion and the second door portion extend linearly. Thus, the flip-up state of the rear gate can be easily switched by switching the switching means.

As another aspect, the connection means is provided on the left and right sides of the front end of the second door and is rotatable about an axis extending in the left-right direction of the vehicle, and vertically at the left and right edges of the rear opening. The rail may be provided with a recess extending in the direction and into which the roller is inserted.
Thereby, the connecting means can be realized with a simple configuration and without obstructing the vehicle rear view.
