Claims

[Scope of utility model registration request]

A structure for fixing a seal fin that seals between a rotating part and a stationary part divided into two parts, wherein an implant groove having an engagement strip is formed on the inner circumferential surface of the stationary part,
The seal fin and the fixing piece are divided into two parts, and a concentric toothing line is formed on one surface of the base of the sealing fin, and a toothing line that fits into the toothing line of the seal fin is formed on one side of the fixing piece. form,
The seal fin and the fixing piece are formed so that the cross-sectional shape when they are meshed with each other at the tooth engagement strips fits into the cross-sectional shape of the implant groove of the stationary part, A seal fin fixing structure characterized in that the seal fin is fixed by being inserted circumferentially into the implant groove from the mating surfaces of the two halves.
