To provide a backdoor structure, in which a convex shape part is provided in a frame member so that a junction structure can be set without influencing a design surface of a panel member serving as an exterior, and uniform thicknesses of an adhesive can be kept so as to secure sufficient adhesion strength.SOLUTION: A backdoor structure comprises a frame member 2 having a shape corresponding to a back door 1 and a panel member 4 joined to an outer side surface of the frame member 2 using an adhesive 3. On the outer side surface of the frame member 2 is provided a convex shape part 51 protruding toward the panel member 4, and the convex shape part 51 is provided continuously along a shape of an outer periphery part of the frame member 2. The adhesive 3 is applied along the convex shape part 51, between the outer periphery part of the frame member 2 and the convex shape part 51. Between the outer periphery part of the frame member 2 and the convex shape part 51 is provided a predetermined interval s, formed by the convex shape part 51, and enabling the applied adhesive 3 to have a predetermined thickness t2.SELECTED DRAWING: Figure 5
【課題】フレーム部材に凸形状部を設けることにより、外装となるパネル部材の意匠面に影響を与えることなく接合構造を設定することができ、接着剤の厚みを均一に保ち、十分な接着強度を確保することなどにある。【解決手段】バックドア1と対応した形状を有するフレーム部材2と、フレーム部材2の外側面に接着剤3を用いて接合されるパネル部材4を有しているバックドア構造において、フレーム部材2の外側面には、パネル部材4へ向かって突出する凸形状部51が設けられ、凸形状部51は、フレーム部材2の外周部の形状に沿って連続して設けられ、接着剤3は、フレーム部材2の外周部と凸形状部51との間で、凸形状部51に沿って塗布されており、フレーム部材2の外周部と凸形状部51との間には、凸形状部51によって形成され、塗布された接着剤3に所定の厚みt2を持たせる所定の間隔sが設けられている。【選択図】図5
