Claims

[Scope of utility model registration request]

A cylindrical shell is rotatably supported by a shaft inserted concentrically through the cylindrical shell, and a pressurizing chamber extending in the axial direction into which a pressure medium is press-fitted between the opposing peripheral surfaces of the two is defined. In a certain roll, there is provided a sealing device for shielding and sealing both ends of the pressurizing chamber in the circumferential direction along the axial direction, and the sealing device is provided on the shaft side so that the cross-sectional shape of the tip end is tapered. A seal body extending in the direction of the housing axis is supported with the side surface of the tip facing the pressure chamber being inclined so as to be slidable in the radial direction of the shell, and the tip of the seal body is attached to the inner circumferential surface of the shell. A sealing device for a roll, characterized in that it is provided with a pressing means for pressing with a predetermined pressure.
