示す。(Prior Art and its Problems) In order to reduce the weight of vehicles, various attempts have been made to improve the structure of the body and its materials. As part of this effort, the applicant has developed a vehicle shown in FIGS. 7 and 8 that uses resin as a body material. FIG. 7 shows a perspective view of the metal frame 1 of the vehicle, and FIG. 8 shows an external perspective view of the resin body 2 assembled to the frame 1.

度が向上することにならない。 In the case of a vehicle having the resin body 2, there are advantages that not only the weight of the vehicle can be reduced, but also the degree of freedom in body design is greatly improved. However, in a vehicle having such a resin body 2, when the back door 3 is enlarged so that its opening extends from the rear end of the rear part to the rear end of the roof as shown in FIG. Considering strength, rigidity, deformation due to wind pressure during driving, etc.
As shown in the figure, a large number of reinforcing members 4a, 4b,
4c needs to be attached, which poses a problem that does not necessarily lead to weight reduction. On the other hand, if an attempt is made to reduce the weight by reducing the number of reinforcing members 4a to 4c, the shape of the back door 3 will be restricted from the viewpoint of strength, etc., and the degree of freedom in body design will not improve.

１１からの水の侵入も有効に規制できる。 In the resin back door 5 described above, the rib 13 integrally molded on the inner panel 6 along the opening edge of the luggage opening 11 constitutes a reinforcing member. Sufficient reinforcement is provided by the reinforcing member 8 attached to the lower surface of the outer panel 7. At this time, since the ribs 13 are joined to the outer panel 7, a greater reinforcing effect can be exerted compared to a case where they are not joined. In addition, when the ribs 13 are formed on the outer panel 7 side, shrinkage may occur on the outer surface of the outer panel 7 corresponding to the ribs 13 during molding, which may result in poor appearance. Since it is molded, it does not affect the appearance in any way. Furthermore, if the rib 13 is formed to protrude downward toward the outer panel 7 side, additional measures are required to prevent water from entering between the lower edge of the rib 13 and the upper surface of the inner panel 6. , an upwardly protruding rib 13 joined to the outer panel 7 is attached to the inner panel 6.
Since the ribs 13 are integrally molded with each other, the ribs 13 function as a bank, as shown in FIG. 4, and can effectively prevent water from entering between the inner panel 6 and the outer panel 7 from the rat gauge opening 11.

Further, although a structure in which the reinforcing member 8 is attached along the front edge of the back side of the outer panel 7 is shown, a structure in which the reinforcing member 8 is attached to the inner panel 6 side may also be used, and sufficient reinforcement can be obtained. It may be determined as appropriate.

ンの自由度向上を達成できる。(Effect of the invention) As described above, according to the resin back door of the vehicle of this invention, the luggage door is arranged at the rear of the back door, and the luggage door is integrally molded along the opening edge of the luggage opening formed there. Since the rib acts as a reinforcing member, sufficient reinforcement is provided by this rib and the reinforcing member attached along the front edge of the back door, and reinforcing members such as the middle part and rear edge of the back door can be omitted. By using a small number of reinforcing members, it is possible to create a resin back door with sufficient strength and rigidity and a large shape, making it possible to reduce the weight of the body and increase the degree of freedom in design.

Since the upwardly protruding ribs that are joined to the outer panel are integrally molded on the inner panel, the ribs have a great reinforcing effect, and there is no risk of spoiling the appearance compared to when ribs are molded on the outer panel side. This has the advantage of effectively restricting water intrusion from the lug gauge opening between the inner panel and the outer panel.
