Claims

[Scope of utility model registration request]

A core shaft that supports the core shaft so as not to rotate and supplies pressurized air to the passage of the shaft core; an extremely thin pipe that is made of a deformable but non-stretchable material and is fitted on the outside of the core shaft; A shape-retaining ring that is fitted into both ends of the pipe to prevent the pipe from deforming, and a shape-retaining ring that protrudes from a predetermined position on the outer periphery of the core shaft located inside the pipe and forms a minute gap between the outer periphery and the inner periphery of the pipe. The annular body provided in the annular body, the pressure distribution discharge part provided on the outer periphery of the annular body to receive air supply from the passage and release the air, and the inside of the pipes on both sides sandwiching the annular body are provided so as to communicate with each other. A roll consisting of a through hole and a valve device that limits the amount of air released through the shape-retaining ring to the atmosphere and maintains a constant pressure within the pipe.
