  Further, at this time, bolt insertion holes 72c formed in the mounting portion 11c of the rear pillar trim 11 and the tip end portion 72b of the second bracket 72 that are overlapped (the rear pillar trim side is not shown in FIG. 6), In addition, the bolt member B1 is inserted into the bolt insertion hole of the inner panel 9 formed corresponding to these holes from the surface side of the rear pillar trim 11, and screwed into a weld nut provided on the inner panel 9 side. To do.

  Further, the resin clip C is inserted into and engaged with the clip insertion hole 11n formed in the lower mounting portion 11m of the rear pillar trim 11 and the clip insertion hole of the inner panel 9 formed corresponding to the hole.

  Then, a lid 16 (see FIG. 2) is attached to the recess 11d of the rear pillar trim 11 to cover the co-tightening bolt B2. Further, the trunk side upper trim 12 is attached to the vehicle body. By doing so, the tightening bolt B1 and the clip C1 are also covered by the trunk side up trim 12. Therefore, the aesthetics are sufficiently secured.

  Then, the attachment of the sub assembly to the vehicle body is completed.

  As described above, according to the present embodiment, the guide rail 41 and the interlocking mechanism 40 are configured as an integral assembly, and are sub-assembled to the rear pillar trim 11 as a sub-assy body. Is assembled to the vehicle body. Therefore, the trouble of individually assembling the various parts constituting the tonneau cover device 10 with respect to the vehicle body is greatly reduced, and the assemblability of the tonneau cover device 10 is greatly improved.

  Further, the bracket 57 for attaching the holder member 58 needs to be exposed to the surface side of the trim 11 through the slit 11r of the rear pillar trim 11, but in this embodiment, it is attached in advance to the rear pillar trim 11 side. Therefore, dimensional accuracy can be tightened, and the width of the slit 11f can be reduced. That is, for example, when a guide rail or the like is attached to the vehicle body side, it is necessary to loosen the dimensional accuracy and increase the width of the slit, so that the appearance is likely to deteriorate, but in this embodiment, Such a situation is prevented.

  Further, the assembly can be attached to the vehicle body in a state where the assembly is fixed to the rear pillar trim 11. That is, even if the sub-assemblies are configured, if the assembly is not fixed to the trim 11, the sub-assemblies may be disassembled during transportation or attachment to the vehicle body. In such a case, such a fear is eliminated.

  Further, the fixing portions 11c, 72b, 11d, 73b provided in the rear pillar trim 1 and the assembly are fastened together with bolts B1, B2 (fastening members) to the vehicle body, so that the rear pillar trim 1 and the assembly are assembled. It is possible to reduce the trouble of fastening the to the vehicle body.

  Further, the holder member 58 attached to the slider 41 can be attached integrally, and it is not necessary to attach it when assembling to the vehicle body.

  Further, the connecting member 52 can be attached integrally, and it is not necessary to attach it when assembling to the vehicle body.
