The structure of the entire mechanical device is simplified as an outside seal. The mechanical sealing device includes a two-half stationary seal ring having a first sealing face at one end and retained fluid-tightly by the housing so as to be movable axially, and a first two-half fastening ring fitting to the outer face of the two-half stationary seal ring and closely contacting the splitting faces of the two-half stationary seal ring. The axial splitting faces of the first two-half fastening ring are coupled. A gap through which the sealed fluid passes is defined between the inner face of the two-half stationary seal ring and the rotational shaft. The two-half stationary seal ring is elastically biased against the two-half rotational seal ring.
