To provide a propeller for a ship propulsion apparatus which is easy to assemble/disassemble and that maintainability is high, and which reliably reduces an impact force transmitted to a shaft shell and to an output shaft of an outboard engine due to contact with a foreign matter.SOLUTION: A propeller 3 for a ship propulsion apparatus comprises a shaft tube 21 fixed in insertable and removable state, to a propeller shaft 11 of the ship propulsion apparatus, a plurality of blades 23 individually supported by the shaft tube 21, lined up next to each other with a gap 22 and in the rotating direction of the propeller shaft 11, and a plurality of dampers 25 provided between adjacent wings 23.SELECTED DRAWING: Figure 4
【課題】組立や分解が容易で整備性が高く、かつ、異物との接触によって軸殻や船外機の出力軸へ伝わる衝撃力を確実に減少させる船舶推進装置用プロペラを提案する。【解決手段】船舶推進装置用のプロペラ3は、船舶推進装置のプロペラシャフト11に挿抜可能に固定される軸筒21と、軸筒21に個別に支持され、かつ隣どうしが隙間22を空けてプロペラシャフト11の回転方向へ並ぶ複数の翼部23と、隣り合う翼部23の間に設けられる複数のダンパー25と、を備えている。【選択図】 図4
