A coupling structure is provided which can be used even when drive shafts cannot be provided on their end with a stopper. The coupling structure allows the drive shafts to be coupled to a differential assembly, requiring a manipulation only from outside the differential case to assure that the drive shafts are coupled to each other so as not to be movable in the direction of the axle shaft. The coupling structure includes a pair of right and left coupling heads and a coupling shaft. Each of the coupling heads has a coupling hole at the point of intersection of the axial line of pinion shafts provided in the differential assembly and the axial line of a pair of right and left drive shafts. The coupling heads are added to the drive shafts via a connector, respectively, to be rotatable about the axle shaft and not movable in the direction of the axle shaft, with the end portion of the coupling heads being disposed in a coupling ring of a cross shaft. The coupling shaft penetrates the through holes of the pair of pinion shafts and the coupling holes of the pair of right and left coupling heads.
