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 and a leakage receiver arranged below the packing holder, a space is provided on the inner periphery of the holder part, spaced apart from the rotating shaft, so as to end from the outside, and from the lower end of the inner periphery of the space to the flange end. A through hole is provided in the rim so that it is located directly above the groove of the leakage liquid receiver, and a through hole is provided above the groove of the leakage liquid receiver on the edge of the flange of the packing holder, pointing downward from the edge of the flange toward the leakage liquid receiver. A seal holder for a shaft sealing device with a protrusion.
