  Relying upon the equivalence between a gauge theory for the translation group
and general relativity, a teleparallel version of the original Kaluza-Klein
theory is developed. In this model, only the internal space (fiber) turns out
to be five dimensional, spacetime being kept always four dimensional. A
five-dimensional translational gauge theory is obtained which unifies, in the
sense of Kaluza-Klein theories, gravitational and electromagnetic interactions.
