Document Type and Number:
Japanese Patent JP7329496
Kind Code:
B2
Abstract:
A sealing apparatus which is capable of preventing static leakage of a target to be sealed without increasing sliding resistance with respect to a shaft, and a surface processing method of a disk member of the sealing apparatus which is capable of easily processing a surface of the disk member such as a slinger provided at the sealing apparatus, are provided.A surface processing method of a disk member of a sealing apparatus for forming a plurality of fine spiral grooves on a surface (31d) of the disk member (3) provided at the sealing apparatus is characterized in that a grinding member (64) having a plurality of fine projections is moved to an outer edge side (arrow c) while the grinding member (64) is pressed against the surface (31d) of the disk member (3) which relatively rotates around an axis (y), and a sealing apparatus is characterized by including a slinger (3) at which a plurality of fine spiral grooves are randomly formed on another side surface of a flange portion.
