Abstract
A propeller shaft includes a shaft section connected between an input shaft and an output shaft via respective constant velocity joints, wherein the input shaft is connected to a drive source of a vehicle, and the output shaft is connected to driving wheels. The constant velocity joint includes a circlip-restricting surface to engage with a circlip provided in an outer peripheral surface of the input or output shaft, for restricting movement of the first or second shaft in an axial direction. The circlip-restricting surface is implemented by a first inclined surface and a second inclined surface, wherein the second inclined surface is closer to a rotational axis of the shaft section, and wherein the first inclined surface has an acute angle with respect to the axial direction, and the second inclined surface has a smaller angle with respect to the axial direction.
