To provide a vehicular roof structure that can prevent intrusion of water into a vehicle interior through an opening with high certainty even if large extension/contraction occurs in a base panel, while achieving reduction in weight and easiness in manufacturing, and suppress occurrence of erroneous operation.SOLUTION: The roof structure according to the invention comprises: a base panel 3 made of resin having an opening 33 formed; an opening/closing panel 5; an opening/closing mechanism 7; and an inner weather strip 9 and first and second outer weather strips 11 and 13 as weather strips. The opening/closing mechanism 7 has a mechanism main body 71 which is attached with the opening/closing panel 5 and a water receiving member 73, arranged in the opening 33, which can store water. A linear thermal expansion coefficient of the mechanism main body 71 and a linear thermal expansion coefficient of the water receiving member 73 are set to be smaller than a linear thermal expansion coefficient of the base panel 3. The inner weather strip 9 and the first and second outer weather strips 11 and 13 are fitted to the water receiving member 73.SELECTED DRAWING: Figure 3

    【課題】軽量化及び製造の容易化を実現しつつ、ベースパネルに大きな伸縮が生じても、開口から車室内への水の浸入を確実性高く防止可能であり、かつ、誤作動の発生を抑制可能な車両用ルーフ構造を提供する。【解決手段】本発明のルーフ構造は、開口33が形成された樹脂製のベースパネル3と、開閉パネル5と、開閉機構7と、ウェザーストリップとしての内側ウェザーストリップ9及び第1、2外側ウェザーストリップ11、13とを備えている。開閉機構7は、開閉パネル5が取り付けられる機構本体71と、開口33内に配置されて水を貯留可能な水受け部材73とを有している。機構本体71の線熱膨張係数と、水受け部材73の線熱膨張係数とは、ベースパネル3の線熱膨張係数よりも小さくされている。内側ウェザーストリップ9及び第1、2外側ウェザーストリップ11、13は、水受け部材73に装着されている。【選択図】図3
