wherein a drainage path is defined along the vehicle width direction of the vehicle body between the adhesive sealers adjacent to each other on upper surfaces of the upper rail panels.
9 . The roof structure of claim 8 , wherein:
the upper rail panel, of each of the plurality of roof rail assemblies, comprises an upper flange portion disposed on both edge portions along the front to rear direction of the vehicle body and an upper rail portion disposed between the upper flange portions; and
the lower rail panel, of each of the plurality of roof rail assemblies, comprises a lower flange portion disposed on both edge portions along the front to rear direction of the vehicle body and a lower rail portion disposed between the lower flange portions.
10 . The roof structure of claim 9 , wherein:
the upper flange portion and the lower flange portion are connected to each other; and
a closed space is defined between the upper rail portion and the lower rail portion.
11 . The roof structure of claim 9 , wherein the module mounting unit comprises:
a mounting bracket connected to a lower surface of the base provided in the roof module;
an engage bolt fixed to the mounting bracket so as to pass through the upper flange portion and the lower flange portion connected together in the vertical direction; and
a fastening nut engaged with the engage bolt.
12 . The roof structure of claim 9 , wherein the module mounting unit comprises:
a mounting bracket connected to a lower surface of the base provided in the roof module;
an engage bolt fixed to the mounting bracket to pass through the upper rail portion along the vertical direction; and
a fastening nut penetrating the lower rail portion and engaged with the engage bolt.
13 . The roof structure of claim 8 , wherein the roof module comprises a plurality of roof modules, and wherein the roof structure further comprises a weather strip provided between the roof modules that are disposed adjacent to each other.
14 . A roof structure for a vehicle, the roof structure comprising:
a plurality of roof rail assemblies each comprising an upper rail panel and a lower rail panel connected to each other, each of the plurality of roof rail assemblies extending along a vehicle width direction of a vehicle body with each end respectively being connected to one of a pair of side structures extending along each side of the vehicle body in a front to rear direction of the vehicle body;
a plurality of roof modules disposed in the front to rear direction of the vehicle body and connected to respective ones of the plurality of roof rail assemblies;
