To provide a propeller shaft in which a first propulsion shaft and a second propulsion shaft can be connected without variously processing the second propulsion shaft.SOLUTION: A propeller shaft comprises a first propulsion shaft, a second propulsion shaft, and a joint part connecting the first propulsion shaft and the second propulsion shaft. The joint part comprises: a joint body part comprising a first end part connected to the first propulsion shaft, and a second end part provided on the side opposite to the first end part, in which a male spline part provided along a rotation axis of the propeller shaft is formed in an outer periphery, in the direction of the rotation axis of the propeller shaft; a cylindrical adapter member comprising a female spline engaged with the male spline, in an inner periphery, and an insertion hole provided at a position opposed to the female spline, into which the second propulsion shaft is inserted, in the direction of the rotation axis of the propeller shaft; and a fixing member provided on the second propulsion shaft for fixing the adapter member and the second propulsion shaft.SELECTED DRAWING: Figure 1 【課題】 第２推進軸に様々な加工をすることなく、第１推進軸と第２推進軸を接続可能なプロペラシャフトを提供することにある。【解決手段】 第１推進軸と第２推進軸と前記第１推進軸と前記第２推進軸を接続するジョイント部を有するプロペラシャフトにおいて、ジョイント部は、プロペラシャフトの回転軸線の方向において、第１推進軸と接続する第１端部と、第１端部とは反対側に設けられ、外周に前記プロペラシャフトの回転軸線に沿って設けられた雄スプライン部が形成された第２端部とを有するジョイント本体部と、プロペラシャフトの回転軸線の方向において、内周に雄スプライン部と噛み合う雌スプライン部と、雌スプライン部と対向する位置に設けられ、第２推進軸が挿入される挿入孔を有した筒状のアダプタ部材と、第２推進軸に設けられ、アダプタ部材と第２推進軸を固定する固定部材とを備える。【選択図】 図１
