To provide a rotary blade for a flight body with enhanced strength of a connection part between a rotary blade part and a hub part, and an attachment structure of the rotary blade for a flight body to a shaft of a motor.SOLUTION: A rotary blade 1 for a flight body made of resin includes a hub part 2 having a rotary center and three or more rotary blade parts 3 installed radially in an outer periphery of the hub part 2. When the rotary blade 1 for a flight body is viewed from the front, in a connection part 5 between the hub part 2 and the rotary blade part 3, adjacent connection parts 5 are viewed as overlapping in a part, and a front edge part 32a of one rotary blade part 32 and the other rotary blade part 31 in a portion of the connection part 5 viewed as overlapping are connected by a rib part 6.SELECTED DRAWING: Figure 2
【課題】回転翼部とハブ部との連結部の強度を高めた飛行体用回転翼及び飛行体用回転翼のモータのシャフトへの取付構造を提供する。【解決手段】回転中心を備えたハブ部2と、ハブ部2の外周に放射状に配設される3枚以上の回転翼部3を備える樹脂製の飛行体用回転翼1であって、飛行体用回転翼1を正面から見たい時に、ハブ部2と回転翼部3との連結部5において、隣接する連結部5は、一部が重なって見え、連結部5の重なって見える部分における、一方の回転翼部32の前縁部32aと他方の回転翼31部とは、リブ部6で連結されている。【選択図】図2
