To provide a propeller shaft for a vehicle which maintains the lubricity of a portion to which a first hollow shaft and a second hollow shaft are fit, and suitably reduces an amount of a lubricant which is filled into the propeller shaft for the vehicle.SOLUTION: A propeller shaft comprises a grease cover 38 for dividing an internal space of a first hollow shaft 30 into a grease holding chamber B for holding grease Gr and a vacant chamber C not for holding the greased Gr. Therefore, even if the grease Gr is filled so that the inside of the propeller shaft 20 is fulfilled with the grease Gr, the vacant chamber C which does not hold the grease Gr in the internal space of the first hollow shaft 30 is formed of the grease cover 38, so that the lubricity of a portion to which external peripheral spline teeth 30b of the first hollow shaft 30 and internal peripheral spline teeth 32b of the second hollow shaft 32 are spline-fit can be maintained, and an amount of the grease Gr which is filled into the propeller shaft 20 can be suitably reduced.SELECTED DRAWING: Figure 4

    【課題】第1中空シャフトと第2中空シャフトが嵌合する部分の潤滑性を維持させ且つ車両用プロペラシャフト内に充填する潤滑油の量を好適に低減させる車両用プロペラシャフトを提供する。【解決手段】第1中空シャフト30の内部空間を、グリスGrを保持するグリス保持室Bと、グリスGrを保持しない空室Cとに分割するグリスカバー38が備えられている。このため、プロペラシャフト20内をグリスGrで満たすようにグリスGrを充填しても、グリスカバー38によって第1中空シャフト30の内部空間にグリスGrを保持しない空室Cが形成されるので、第1中空シャフト30の外周スプライン歯30bと第2中空シャフト32の内周スプライン歯32bがスプライン嵌合する部分の潤滑性を維持させ且つプロペラシャフト20内に充填するグリスGrの量を好適に低減させられる。【選択図】図4
