Claims

[Scope of utility model registration request]

A round hole is provided on the casing side on the outer periphery of the insertion part of the rotating shaft,
A shaft sealing material is inserted between the round hole and the rotating shaft, and the shaft sealing material is pressed in the axial direction by a packing holder that has a holding part and a flange that fit into the round hole and the flange is attached diagonally, thereby sealing the rotating shaft. In a shaft sealing device with a leakage liquid receiver placed below the seal holder, a space is provided on the inner periphery of the holder with a space between it and the rotating shaft so as to stop from the outside, and leakage from the flange edge of the seal holder is provided. A gasket retainer for a shaft sealing device, which has a protrusion extending downward from the edge of the flange toward the leakage liquid receiver above the inside of the liquid receiver.
