To provide a wing body that improves the thrust of a flapping device.SOLUTION: A wing body 4A has a frame body 70, and a sheet body 80 that is flexible, is attached to the frame body 70, and forms a wing surface. The sheet body 80 includes a first root portion 81, a second root portion 82, a tip portion 83, a first edge portion 84, and a second edge portion 85. The second edge portion 85 extends from the second root portion 82, and includes a first area 85a extending in a direction orthogonal to the direction in which the first edge portion 84 extends, a second area 85b connected to the first area 85a, and a third area 85c that is connected to the second area 85b and extends to the tip portion 83. The sheet body 80 between the first root portion 81 and the second root portion 82 is provided with a slit S including a third edge portion 86 that extends between the second root portion 82 and a slit end P, and a fourth edge portion 87 that is connected to the third edge portion 86 and extends between the slit end P and the first root portion 81.SELECTED DRAWING: Figure 5
【課題】羽ばたき装置の推力を向上させる羽体を提供する。【解決手段】羽体4Aは、枠体70と、可撓性を有し、枠体70に取り付けられ、羽面を形成するシート体80とを備えている。シート体80は、第1付け根部81と、第2付け根部82と、先端部83と、第1縁部84と、第2縁部85とを含む。第2縁部85は、第2付け根部82から延び、第1縁部84の延びる方向と直交する方向に延びる第1領域85aと、第1領域85aに接続される第2領域85bと、第2領域85bに接続され、先端部83まで延びる第3領域85cとを含む。第1付け根部81と第2付け根部82との間のシート体80には、第2付け根部82とスリット端部Pとの間に延びる第3縁部86と、第3縁部86に接続され、スリット端部Pと第1付け根部81との間に延びる第4縁部87とを含むスリットSが設けられている。【選択図】図5
