[Problem] The present invention relates to a fall-off preventing structure of a propeller shaft, and it is a proposal thereof to provide a fall-off preventing structure which does not allow a companion flange to be completely pulled off and drop from a spline shaft when a nut loosens and comes off. [Solution to Problem] In the propeller shaft, a spline engagement length of the companion flange and a spline shaft of a first propeller shaft is shorter than a tolerable slide amount of a spline yoke and a spline shaft of a second propeller shaft, in which a round shaft part is provided on a front end of the spline shaft on which a nut is screwed, a length of a threaded part of the spline shaft front end side on which the nut is screwed and the round shaft part is set longer than a length from a front end portion of the companion flange to a seat surface of the nut, and a total length of the length of the threaded part and the round shaft part and a length from the front end portion of the companion flange to the seat surface of the nut is set longer than the tolerable slide amount.
