Claims

[Scope of utility model registration request]

A pressing roll that presses an abrasive tape of a predetermined width against the polishing surface of an object to be polished, which is driven at high speed, with the width direction of the abrasive tape and the direction of the center axis being the same, and the roll has a truncated conical core material. and a rubber-like elastic body that is attached around the core material and has a cylindrical shape.
