To provide a propeller obtaining both of rattle sound suppression and shift shock suppression and a vessel propeller including the same.SOLUTION: A propeller 22 includes a bush 41, a propeller body 42, and a propeller damper 45. The bush 41 includes a first cylindrical unit 51 surrounding the propeller shaft 15, and a first projection 52 provided on an outer periphery surface 51C of the first cylindrical unit 51. The propeller body 42 includes a second cylindrical unit 60 surrounding the bush 41, and a second projection 62 provided on an inner periphery surface 60A of the second cylindrical unit 60. The first projection 52 and the second projection 62 are lined up along a rotational direction S. The propeller damper 45 includes a first damper 71 and a second damper 72 arranged lined up along an axial direction X between the first cylindrical unit 51 and the second cylindrical unit 60. The first damper 71 and the second damper 72 are capable of being elastically deformed individually by being separated from each other by a separation unit 73.SELECTED DRAWING: Figure 2

    【課題】ラトル音抑制及びシフトショック抑制の両立を図れるプロペラ、及び、これを含む船舶推進機を提供する。【解決手段】プロペラ22は、ブッシュ41と、プロペラ本体42と、プロペラダンパ45とを含む。ブッシュ41は、プロペラシャフト15を取り囲む第1筒部51と、第1筒部51の外周面51Cに設けられた第1突起52とを有する。プロペラ本体42は、ブッシュ41を取り囲んだ第2筒部60と、第2筒部60の内周面60Aに設けられた第2突起62とを有する。第1突起52と第2突起62とは、回転方向Sに沿って並ぶ。プロペラダンパ45は、第1筒部51と第2筒部60との間において軸方向Xに沿って並んで配置された第1ダンパ71及び第2ダンパ72を有する。第1ダンパ71及び第2ダンパ72は、分離部73によって互いから分離されて個別に弾性変形可能である。【選択図】図2
