Claims

[Scope of claim for utility model registration] A pair of vertical chains consisting of a link chain,
In a tire chain that is formed into a rope ladder shape by a horizontal chain and is wrapped around the outer circumference of a tire, the end of the vertical chain has a hook connection part consisting of a hook link at one end and a latching link at the other end,
The hook link has a bulge formed at its tip, and the latching link has a bulging hollow portion that allows the bulge to pass through the bulge only when the hook link is rotated in a tightened latching position. Further, a separate temporary locking member having a hook link temporary locking portion at a position on the inside of the tire is provided on the elastic holding piece that can be freely attached and detached transversely to the outer periphery of the tire. The hook link of the vertical chain is provided with a locking part that engages with the temporary locking part, and is further provided with a separate tightening ring made of an elastic ring with a group of tightening hooks projecting outward, A tire chain characterized in that the tightening hook has a tapered leg piece at its tip that hooks each pair of chain links of the vertical chain wrapped around the outside of the tire and brings the pair of chain links closer together. .
