Abstract

PURPOSE: In a shaft sealing device based on a labyrinth seal, to reduce production cost by forming the labyrinth seal portion with a material different from that forming a support.
CONSTITUTION: A labyrinth seal 11 has inner projections and is pressure fitted in a support 12. The interference of the labyrinth seal 11 is set such that a frictional force in excess of the pressure of liquid sealed for moving the seal 11 in the axial direction is produced between the seal 11 and support 12.
