And the outer panel 14 are joined.

<Operation and Effect of First Embodiment>
Next, the operation and effect of the present embodiment will be described.

  In the luggage door 10 having the above-described configuration, the entire outer panel 14 is formed of a synthetic resin material, and is lighter than a configuration in which resin parts (for example, a resin finisher in Patent Document 1) are provided on a metal outer panel. In addition, since the number of parts can be reduced, the parts cost and assembly cost can be greatly reduced.

  Further, the outer panel 14 is formed in a flat or curved surface on the outer surface from the viewpoint of airflow flowing on the surface while the vehicle is traveling, appearance (appearance), and the like, and a structure for supplementing the rigidity of the bead portion and the like. It is difficult to form. On the other hand, unlike the outer panel 14, the inner panel 12 is normally not visible from the outside of the vehicle. In addition, in the state where the luggage door 10 is closed at the opening of the trunk room, the surface of the inner panel 12 faces the inner side of the trunk room, so that the airflow generated during traveling of the vehicle is not affected.

  Therefore, even if the inner panel 12 forms a structure for supplementing rigidity, such as the bead portion 26, there is no problem. For this reason, the rigidity of the outer panel 14 can be increased by fixing the outer peripheral portion of the outer panel 14 to the inner panel 12 that can sufficiently compensate for the rigidity and can resist external forces from various directions. . Moreover, since the inner panel 12 and the outer panel 14 are joined by fixing the entire outer peripheral portion of the outer panel 14 to the inner panel 12, the joining strength between the inner panel 12 and the outer panel 14 is also increased. Further, unlike the conventional configuration disclosed in Patent Document 1, the outer panel 14 entirely formed of a synthetic resin material does not have to be formed in the outer panel 14 with a cut-out portion for assembling resin parts. The outer panel 14 itself does not deteriorate in rigidity.

  Further, the outer panel 14 is fixed not only to the outer peripheral portion thereof but also to the back surface of the panel upper portion 42 in the vicinity of the panel bending portion 44, and the support body 60 is fixed to the panel upper portion from the back surface side of the panel upper portion 42. 42 is supported. For this reason, the rigidity of the outer panel 14 can be improved even in the vicinity of the panel bending portion 44 of the panel upper portion 42 that is separated from the outer peripheral portion of the inner panel 12. For example, when the luggage door 10 is closed at the opening of the trunk room, the outer panel is viewed from above. Even when an external force acts on 14, the panel upper part 42 (outer panel 14) can be prevented or effectively prevented from being greatly bent.

  In the present embodiment, the entire outer peripheral portion of the outer panel 14 and the contact portion of the flange portion 38 are integrally fixed. However, the outer panel 14 has a configuration in which the entire outer peripheral portion is fixed to the flange portion 38. For example, the outer panel 14 may have a configuration in which only the predetermined portion of the outer peripheral portion is fixed to the flange portion 38 at predetermined intervals.

  In the luggage door 90 configured as described above, the portion corresponding to the panel bending portion 44 and the panel rear portion 46 of the outer panel 14 in the first embodiment, that is, the portion corresponding to the panel upper portion 42 of the outer panel 14 is a metal. The panel metal part 94 is made of. Therefore, in the luggage door 90, the panel metal part 94 has higher rigidity than the panel upper part 42, and one side in the thickness direction of the panel metal part 94 (that is, the luggage door 90 closed the opening of the trunk room). It is possible to prevent or effectively suppress the bending with an external force from the vehicle upper side in the state.

  Further, in the outer panel 92, the panel resin portion 102 is made of resin. However, in the outer panel 14 in the first embodiment, the panel resin portion 102 forms the panel rear portion 46. For this reason, in the state where the luggage door 90 closes the opening of the trunk room, the thickness direction of the panel resin portion 102 is along the longitudinal direction of the vehicle, so that the panel resin portion 102 has high rigidity with respect to external force from the vehicle upper side. . For this reason, it is possible to prevent or effectively suppress the outer panel 92 including the panel resin portion 102 from being bent by an external force from the vehicle upper side.

Next, a third embodiment of the present invention will be described.

  FIG. 14 shows an outer panel 162 constituting the luggage door 160 according to the present embodiment in a perspective view from above.

  The outer panel 162 shown in this figure includes a panel metal portion 164. The panel metal part 164 is formed by press-molding a metal flat plate (for example, a steel plate as an example) and plastically deforming it into a desired shape, and further includes a panel upper part 96 and a panel bending part 98. The configuration is basically the same as that of the panel metal portion 94 in the second embodiment. However, unlike the panel metal part 94, the panel metal part 164 includes an extension piece 166 as an extension part. The extension piece 166 is generally located at the upper side of the panel from the end opposite to the panel upper part 96 of the panel bending part 98 on both sides of the panel bending part 98 along the left-right direction of the vehicle with the luggage door 160 attached to the vehicle. 96 extends along the thickness direction.

  A rectangular opening 168 is formed in these extended pieces 166. As shown in FIG. 15, which is a cross-sectional view of the extended piece 166 and its vicinity viewed from the left side of the vehicle, a cup-shaped lamp house 170 is disposed in the opening 168 so as to penetrate the lamp house 170. The lamp house 170 is attached to the luggage door 160 by fixing the flange portion 172 formed at the opening end to the extending piece 166.

  On the other hand, as shown in FIG. 14, the luggage door 160 includes a panel resin portion 174 as a resin portion. The panel resin portion 174 is formed by molding a synthetic resin material into a desired shape as a whole. Basically, the panel upper portion 42 and the panel bending portion 44 are not formed, but the panel rear portion 46 is formed. Is the same configuration as the panel resin portion 102 in the second embodiment.

  However, in the panel resin portion 174, a cut portion 176 is formed in the panel rear portion 46. The cut portion 176 is formed corresponding to each of the extended pieces 166 described above, and the extended piece 166 enters the cut portion 176 when the panel metal portion 164 and the panel resin portion 174 are joined. Further, a vertical wall portion 178 extends from each cut portion 176 toward the extending piece 166 side. As shown in FIGS. 14 and 15, a plate-like fixing portion 180 facing the extending piece 166 in the thickness direction is formed at the end of the vertical wall portion 178 on the extending piece 166 side. The fixing portion 180 is fixed to the extending piece 166 in a state where it is in contact with the extending piece 166.

<Operation and Effect of Third Embodiment>
Next, the operation and effect of the present embodiment will be described.

  The main luggage door 160 configured as described above is basically the same in structure as the luggage door 90 according to the second embodiment except that the extended piece 166 and the cutout portion 176 are provided. The 160 has basically the same action as the luggage door 90 and can basically obtain the same effect as the luggage door 90.

  In addition, as described above, the luggage door 160 is formed with the extended piece 166 for attaching the lamp house 170 to the outer panel 162 formed by metal press molding having higher dimensional accuracy and the like than resin molding. For this reason, the dimensional accuracy etc. of the extended piece 166 are high, Therefore, the installation accuracy of the panel metal part 164 and the lamp house 170 can be improved. In addition, since the fixing portion 180 on the panel resin portion 174 side is fixed to this 0066, the accuracy of mounting the panel resin portion 174 and the lamp house 170 can be improved.
