Claims

[Scope of utility model registration request]

In a sealing device in which a seal ring is fitted into an annular groove formed in a rotating shaft, one side of the seal ring and an inner corner surface of a bearing box of a bearing rotatably supporting the rotating shaft are tapered with the same slope. a surface is provided, the tapered surface of the seal ring and the receiving box are brought into close contact, and the contact surface is provided with:
A reaction force is generated in the axial direction of the rotating shaft due to the tension of the seal ring, and the seal ring is moved into the annular groove.
A sealing device characterized in that the seal ring is pressed toward a groove wall on a side opposite to the tapered surface of the seal ring.
