摘要： PROBLEM TO BE SOLVED: To provide a structure of a sealing device which can surely supplement grease over a wide area in a grease sealed space while allowing the discharge of the grease in supplementing the grease.
SOLUTION: In an inner seal 2 of the sealing device 1, a through hole 28 for grease discharge is formed in the middle in the upper radial direction of an annular plate 24 of an annular core metal 21. By this, when supplementing the grease to a target to be sealed, new grease to be poured is sequentially retained from the lower part of the target to be sealed and old grease is discharged sequentially from the upper part of the sealing device 1, and the new grease and the old grease can be easily replaced and the new grease easily reaches the wide area in the target to be sealed.
