Resin roof
A resin roof is provided with a main roof and a sub-roof. The main roof includes an outer layer fabricated of resin, which structures a roof panel of a vehicle, and an inner layer fabricated of foam resin, which is provided in a predetermined region that excludes a peripheral edge portion of the outer layer. The sub-roof is fabricated of resin and provided at a vehicle body side. In plan view, the sub-roof is provided between a left and right pair of roof side rails of the vehicle. A joining portion at the peripheral edge portion of the outer layer is joined to the sub-roof. Thus, together with the outer layer, the sub-roof structures the roof panel.
