[Prior art]

 Tire chains are widely used as a non-slip device for running on snowy roads of vehicles, but if you do not need to run on snowy roads for a long time, so-called one-touch chains that can be easily attached to and detached from tires are used. .

As this one-touch chain, as shown in Japanese Utility Model Laid-Open No. 60-151740, a non-slip chain is passed between two facing metal fittings and a cloth band band is attached to the metal fittings. In addition, as shown in Japanese Utility Model Laid-Open No. 55-19020, a hook metal fitting is used instead of the cloth band band, and the hook is formed on a tire wheel in advance (actual opening). Japanese Laid-Open Patent Application No. Sho 60-173405) and a device that is simply mounted by sandwiching a tire (Japanese Utility Model Laid-Open No. 3-42703) are known.

[0004]

[Problems to be solved by the device]

 Of the above-mentioned conventional one-touch chains, those that are mounted by sandwiching the tire are not realistic because they easily come off during running. All the other conventional devices require operation processing on the back side of the tire when the tire is mounted. That is, in the case of using the cloth belt band, the band is inserted through the through hole of the wheel so as to be wound around the tire, and at that time, the band must be passed from the back side of the tire to the front side. In addition, all those that do not use a band need to be hooked on the back side of the tire.

Therefore, it is not always an easy task to mount a tire in an emergency, and there is a great possibility that clothes will be soiled during the mounting work. Therefore, the present invention proposes a one-touch chain that does not require operation processing on the back side of the tire.
