置。 For the tapered shaft hole formed in the shaft insertion part on the housing side, where one side has a large diameter, the shaft inserted through the tapered shaft hole is prevented from rotating, and is inserted freely in the axial direction, while at the same time A threaded seal member that constitutes a conical valve seat is inserted into the large diameter end of the formed tapered thread so as to be freely releasable and detachable, and is inserted adjacently to the large diameter side of the threaded seal member with respect to the shaft to form the threaded seal. A sliding end that comes into contact with the shaft and a fixed end that is fixed to the shaft side are connected by a telescopic cylindrical part, and a weight is disposed around the middle of the cylindrical part,
A threaded seal balance mechanism is constructed by elastically pressing the sliding end against the end face of the threaded seal member, and when the shaft rotates, centrifugal force applied to the threaded seal balance mechanism causes the threaded seal member and the tapered shaft hole to become non-sliding. A shaft sealing device characterized by maintaining the condition.
