It has a first-stop spiral groove that is inclined in the direction of drawing fluid from the sealed space into the gap during rotation, and the groove depth of this spiral groove is determined by the sealing surface of both seal members due to the heat of sliding with the fluid in the gap. A non-contact type shaft sealing device characterized in that the depth is gradually deepened toward the sealed space side in response to the amount of deformation of the shaft.
