Claims

[Scope of utility model registration request]

The working fluid from the pump driven by the rotating shaft passes through the shaft penetrating portion of the casing to the driving source due to the sliding surface of the rotating ring that rotates with the rotating shaft passing through the casing and the movable pipe that is pressed from the axial direction. In a sealing device for a shaft penetrating part that prevents intrusion into the shaft,
A sealing device for a shaft penetrating portion, characterized in that a spacer movable in the axial direction is provided between a spring that presses the movable pipe toward the rotating ring and an O-ring attached to the outer periphery of the movable pipe. .
