Resin roof mounting structure
A roof panel made of resin has lower flange portions that are bent toward a vehicle lower side from vehicle side end portions of a upper surface portion. Outer panels that structure roof side rails have groove portions that are concave and are formed along a vehicle longitudinal direction at vehicle transverse direction inner sides of curved surface portions, and inner side flange portions that are formed at final end portions that are further toward vehicle transverse direction inner sides than the groove portions. In a state in which the lower flange portions are disposed within the groove portions of the outer panels, the inner side flange portions of the outer panels and an inner surface of the upper surface portion of the roof panel are joined by an adhesive.
1. A resin roof mounting structure comprising:
a resin roof that is provided at a vehicle upper portion along a vehicle transverse direction and a vehicle longitudinal direction, and that has, at vehicle side portion final ends, flange portions that are bent toward a vehicle lower side or a vehicle upper side;
roof side rails that are provided at upper end portions of vehicle side portions, and that extend in the vehicle longitudinal direction along side end portions of the resin roof;
groove portions that are concave and are provided along the vehicle longitudinal direction at vehicle transverse direction inner side end portions of outer panels that structure the roof side rails, the flange portions being disposed within the groove portions;
joined portions that are provided at final end portions of the outer panels, which final end portions are further toward vehicle transverse direction inner sides than the groove portions, and that are joined to an inner surface of the resin roof in a state in which the flange portions are disposed within the groove portions; and
abutment surfaces that are provided between the groove portions and the joined portions in the vehicle transverse direction of the outer panels, that project out toward the vehicle upper side, and that abut the inner surface of the resin roof.
2. The resin roof mounting structure of claim 1 , wherein
the flange portions are lower flange portions at which vehicle side end portions of the resin roof are bent toward the vehicle lower side, and
the groove portions are shaped, in cross-section, as hats at which the outer panels are recessed toward the vehicle lower side.
3. The resin roof mounting structure of claim 1 , wherein
the flange portions are upper flange portions at which vehicle side end portions of the resin roof are bent toward the vehicle upper side, and
the groove portions are shapes in which vertical wall portions, that are provided at the outer panels, are recessed toward vehicle transverse direction outer sides.
4. The resin roof mounting structure of claim 3 , wherein concave portions, that are recessed further toward the vehicle lower side than the joined portions, are provided along the vehicle longitudinal direction at lower portions of the groove portions.
