[0017]

According to the present invention, the present invention has a structure as described above, is positioned at substantially the center of the side surface of the tire, and is developed by elongating each plate material with the hinge portion as a fulcrum. If the entire length is reduced by locking the bifurcated locking portions at both ends to the tightening ring locked to the edge and folding each plate material so as to overlap, the tightening ring will move toward the center of the tire side. To prevent the tire from slipping and tightening, it is necessary to tighten the anti-slip device sufficiently and securely, and with a little effort, to make it close to the tire, even if the tightening ring does not have an extremely strong restoring force as before. Therefore, even if a person (for example, an elderly person, a woman, etc.) who wears the tire anti-slip device can perform the operation easily and reliably, it is excellent in usability.

Further, since the locking portion is made to have a forked shape to disperse the applied force, the tightening ring is less fatigued and is very useful and of high commercial value.
