Claims

[Scope of utility model registration request]

A winding core for winding a sheet-like material over the entire width, with a protector fixed to both ends that are used by closely fitting onto a single shaft, and the protector includes a flange portion and this core. It consists of a cylindrical part that is perpendicular to the flange part and extends to the center part, and the peripheral part of the flange part has a space between it and the surface of the core body, and furthermore, there is a gap between the surface of the flange part and the core body. A winding core whose end faces form the same plane.
