To provide a roof unit of a vehicle which inhibits occurrence of residual deformation in a roof panel after a baking finishing step, and to provide a manufacturing method of a vehicle including the roof unit.SOLUTION: A roof structure includes: a roof panel made of aluminium and a roof reinforcement 40 made of steel; and a metallic elastic support part 50. The roof panel and the roof reinforcement 40 are joined to a roof side rail made of steel. The elastic support part 50 is disposed between the roof panel and the roof reinforcement 40 and can elastically deform in response to increase or decrease of a distance between the roof panel and the roof reinforcement 40. The elastic support part 50 deforms according to heat expansion and heat shrinkage of the roof panel and the roof reinforcement 40 during a baking finishing step.SELECTED DRAWING: Figure 2A
【課題】焼付塗装工程後のルーフパネルに残留変形が生じることを抑止した自動車のルーフユニット、および当該ルーフユニットを備えた自動車の製造方法を提供する。【解決手段】ルーフ構造体は、アルミニウム製のルーフパネルおよび鋼製のルーフリインフォース40と、金属製の弾性支持部50と、を備える。ルーフパネルおよびルーフリインフォース40は、鋼製のルーフサイドレールに接合される。弾性支持部50は、ルーフパネルとルーフリインフォース40との間に介在し、ルーフパネルとルーフリインフォース40との間隔の増減に応じて弾性変形可能とされる。焼付塗装工程時のルーフパネルおよびルーフリインフォース40の熱膨張および熱収縮に応じて、弾性支持部50が変形する。【選択図】図2A
