Abstract
A method of manufacturing a hollow drive shaft for a vehicle may include swaging one of a first hollow tube and a second hollow tube having a same diameter to reduce an outer diameter thereof and thus allow the swaged hollow tube to be assembled in a remaining hollow tube of the first hollow tube and the second hollow tube, assembling the hollow tube that is reduced in outer diameter in the remaining hollow tube, thereby forming a hollow shaft, and joining first and second stems to both sides of the hollow shaft, respectively.
