Abstract

PURPOSE: To provide even a less flexible cylinder with highly hermetic sealing, by expanding its end like a bell mouth and composing a hermetic guide surface on the inner circumference of the remaining cylinder.
CONSTITUTION: Since a seal ring 2 is composed by expanding one end E of a cylinder in a shape of bell mouth, some force of forming a cone is produced in the remaining portion 3 of the cylinder. As this portion is fitted to a shaft while being expanded little by little, it fits close to the guide surface of the shaft. When the hermetic surface is worn out, the inner diameter of the cylindrical portion is reduced to keep the hermetic seal unchanged. Since little internal stress is produced in the portion 3 or the portion 3 has little internal stress in itself, it can closely and evenly fit to the guide surface of the shaft.
