A propeller shaft for a vehicle includes: a shaft having a plurality of catching protrusions for a spline-connection along an outer peripheral surface; a tube having a plurality of catching grooves along an inner peripheral surface into which the shaft is inserted; a stopper member provided to be fixed to an inner peripheral surface of the tube, one end corresponding to a remote end of the shaft and which is fractured when a collision load is applied thereto; and a locking member one end of which is in contact with one end of the stopper member and which is connected to the shaft and supports both ends of the stopper member together with the shaft, thereby restricting a sliding of the shaft, and which is slid inside the tube together with the shaft when the stopper member is fractured.
