Description of the Related Art Glass used for furniture such as window glasses, side tables, cupboards and the like may be broken by a typhoon, an earthquake, or the like, which is dangerous because it scatters around. In order to avoid such danger, a craft tape or the like is urgently applied to window glass, etc. in the form of a cross, a cross, or a combination of both to prevent damage or scattering in the event of a typhoon or earthquake. doing. Further, when a crack is formed, a tape is similarly attached to prevent the crack from spreading and scattering. However, such a kraft tape has an excessively strong adhesive action on the glass, and when peeled off after use, the adhesive remains attached to the surface of the glass, and is further contaminated with dust and the like.

When affixing to a window glass, etc., the tape is naturally rewound by its own weight, and when the user releases his hand to remove a blade or scissors to cut the tape, or drops the tape. In such a case, the unused material is rewound for a long time, making it difficult to perform the attaching operation, which is often inconvenient.
