To provide a resin roof which can suppress generation of heat strain caused by a difference in coefficients of thermal expansion between an outer layer and an inner layer in a roof body including the outer layer and the inner layer.SOLUTION: A resin roof 10 includes: a roof body 50 including an outer layer 52 that constitutes a roof panel of a vehicle and is made of a resin, and an inner layer 56 that is provided in a predetermined region E excluding a peripheral edge part 52A of the outer layer 52, has a higher coefficient of thermal expansion than that of the outer layer 52 and is made of a resin; a first joint part 54 that is provided in the peripheral edge part 52A of the outer layer 52, and is joined to a first joined part 44 provided in a first base material 40 on a vehicle body side by a first adhesive G1; and a second joint part 58 that is provided in the inner layer 56, and is joined to a second joined part 36F provided in a second base material 30 on the vehicle body side by a second adhesive G2, in which the second adhesive G2 has higher followability than that of the first adhesive G1.SELECTED DRAWING: Figure 3
【課題】アウタ層とインナ層とを含むルーフ本体に、アウタ層とインナ層との熱膨張率の差に起因した熱歪みが発生するのを抑制できる樹脂ルーフを得る。【解決手段】車両のルーフパネルを構成する樹脂製のアウタ層52と、アウタ層52の周縁部52Aを除く所定の領域に設けられ、アウタ層52よりも熱膨張率が高い樹脂製のインナ層56と、を含むルーフ本体50と、アウタ層52の周縁部52Aに設けられ、車体側の第1基材40に設けられた第1被接合部44に第1接着剤G1によって接合される第1接合部54と、インナ層56に設けられ、車体側の第2基材30に設けられた第2被接合部36Fに第2接着剤G2によって接合される第2接合部58と、を備えた樹脂ルーフ10であって、第2接着剤G2は、第1接着剤G1よりも追従性が高くなるように構成されている。【選択図】図3
