A propeller shaft (PS) is provided with a cover member (7), one end of which is fixed to a sleeve shaft (2) and the other end of which is fixed to a stub shaft (3), and a cover strap (8) for fixing the cover member (7) to the sleeve shaft (2) and the stub shaft (3). Protruding parts (74) which are embedded into embedding grooves (26) formed on the outer peripheral surfaces of the sleeve shaft (2) and the short shaft (3) are arranged on the inner peripheral sides of one end part and the other end part of the cover part (7). In particular, in the present invention, on the sleeve shaft (2) and the stub shaft (3), a first outer diameter section (231) having an outer diameter larger than the inner diameter (D1) of the protruding section (74) is provided on the tip side of the fitting groove (26), and a second outer diameter section (232) having an outer diameter larger than the outer diameter (X1) of the first outer diameter section (231) is provided on the base end side of the fitting groove (26).
本发明的传动轴(PS)具有一端部固定于套筒轴(2)、另一端部固定于短轴(3)的罩部件(7)、将罩部件(7)固定于套筒轴(2)和短轴(3)的罩箍带(8)。在罩部件(7)的一端部和另一端部的内周侧设有与在套筒轴(2)和短轴(3)的外周面形成的嵌合槽(26)嵌合的突出部(74)。特别是在本发明中,在套筒轴(2)和短轴(3)上,在与嵌合槽(26)相比更靠前端侧的位置设有与突出部(74)的内径(D1)相比外径更大的第一外径部(231),并且在与嵌合槽(26)相比更靠基端侧的位置设有与第一外径部(231)的外径(X1)相比外径更大的第二外径部(232)。
