To provide a propeller shaft capable of controlling a movement range of a mass body after separation, even if the mass body is separated with respect to a torsional damper disposed near an intermediate bearing.SOLUTION: A propeller shaft is equipped with a rotary member that rotates about a rotary shaft, a torsional damper attached to the rotary member, and an intermediate bearing externally fitted with the rotary member and disposed adjacent to the torsional damper. At least one of the rotary member or the torsional damper is provided with a movement regulating portion that regulates the movement in an axial direction of the rotary shaft of a mass body of the torsional damper.SELECTED DRAWING: Figure 2 【課題】中間軸受の近傍に配置されるトーショナルダンパに対して、質量体が離脱しても、離脱後の質量体の移動範囲を制限することが可能な推進軸を提供する。【解決手段】回転軸を中心として回転する回転部材と、回転部材に取着されるトーショナルダンパと、回転部材に外嵌されるとともに、トーショナルダンパに隣接して配置される中間軸受と、を備え、回転部材、及び、トーショナルダンパの少なくとも一方に、トーショナルダンパの質量体が回転軸の軸方向へと移動することを規制する移動規制部を備える、推進軸。【選択図】図２
