A primary technical goal of this shaft seal device is to decrease the number of seals by means of a pressure reducing floating ring, to integrate the whole unit and to simplify assembly of the device due to its simplified construction. The seal device disposes a fixed sleeve whose outer diameter surface is fitted to the inner diameter surfaces of a first sleeve and a second sleeve and whose inner diameter surface can be fitted over a rotary shaft, said fixed sleeve and said second sleeve being engaged and joined with each other by means of a connecting means.
