PURPOSE:To improve the fitness to a tire and to prevent an inside rope from being broken by forming the inside rope with a metal chain and providing a ring feeding hook on a chain ring between inside connecting members in a nonskid device for a vehicle. CONSTITUTION:A nonskid device is fitted to a tire, with a chain 6 kept inside the tire and a rope 5 outside the tire. In this case, if the chain between inside connecting members 7 has a sag, the chain is hauled in by the number of rings corresponding to the length of the sag and hooked to a ring feeding hook 12. Thereby, nonskid bodies 1 are kept at a uniform distance. According to this constitution, the length can be easily adjusted with a single device, and the distance between the inside connecting members can be unified. In addition, an inside rope can be prevented from being broken by the metal chain. d.
