no. 1 Embodiment approach

[0097] Next, a vehicle rear door structure according to a first embodiment of the present invention will be described in detail with reference to appropriate drawings. In the referenced drawings, figure 1 It is a partial perspective view of a vehicle to which the rear door structure of the first embodiment is applied. figure 2 It is a perspective view showing the state of the inner panel constituting the rear door structure of the first embodiment viewed from the outside of the vehicle. image 3 It is a partial perspective view showing the state from the side part side of the inner panel frame part to the reinforcement part as viewed from the inside of the vehicle. figure 2 The diagram of the site indicated by the arrow C.

[0098] Such as figure 1 As shown, the rear door structure 1a is applied to a rear door 2 that opens and closes a tailgate opening 3 of a vehicle V. As shown in FIG. Incidentally, the rear door 2 has a lift-up structure, that is, its upper edge and ...

no. 2 Embodiment approach

[0115] Next, a vehicle rear door structure according to a second embodiment of the present invention will be described in detail with reference to appropriate drawings. In the attached drawing, Figure 4 It is a perspective view showing the state of the inner panel constituting the rear door structure of the second embodiment viewed from the outside of the vehicle. Figure 5 yes Figure 4 The X-X section view. Figure 6 It is a side view of the inner panel in 2nd Embodiment. and, Figure 6 The state where the hinge is attached to the inner panel is shown, and the vehicle body with the inner panel attached is shown by a phantom line. In addition, since the rear door structure of this embodiment is configured in the same manner as that of the first embodiment except that the inner panel is different from the rear door structure of the first embodiment, in the following description, the inner panel will be mainly described. , and the same reference numerals are assigned to t...

no. 3 Embodiment approach

[0126] In addition, in the above-mentioned second embodiment, the beam 18 is attached as a member separate from the inner panel 6a, but the present invention is not limited thereto. here, Figure 7 It is a perspective view showing the state of an inner panel constituting a rear door structure according to another embodiment, viewed from the outside of the vehicle.

[0127] Such as Figure 7As shown, in the inner panel 6b constituting the rear door structure 1c, the beam 18 extending between the connecting parts 17 and 17 is integrally formed with the inner panel 6b by press molding.

[0128] In the above-mentioned rear door structure 1c, since the beam 18 is integrally formed with the frame portion 9 and the reinforcement portion 10 (10a, 10b), rigidity is improved, and the rear door structure 1c (inner panel 6b) The manufacturing process is simplified.

[0129] In addition, in the above-mentioned embodiment, although the reinforcing parts 10a, 10b extend in a substantially...
