Claims

[Claims for Utility Model Registration] (1) A drum that is coaxially fixed to a tire wheel and rotates as a unit, and a ring-shaped roller support plate placed facing the side of the drum that is supported at intervals. a plurality of rollers that are pressed against the outer peripheral surface of the drum and rotate by friction; a winding shaft that has an outer diameter smaller than the outer diameter of each roller and rotates coaxially with the rollers; A plurality of string-like bodies are connected at one end to the winding shaft and have hooks at the other ends that are hooked to the edge of the anti-slip body attached to the tread surface of the tire, and the string-like body is connected to the rotation of the tire. 1. A tightening device for a tire anti-slip device, characterized in that a roller is frictionally rotated in a direction opposite to the rotational direction of a tire via an anti-slip main body that rotates with a deviation in the opposite direction. (2) The tire slip according to claim (1), wherein the winding shaft is fitted to the roller so as to be frictionally rotatable, and the roller is pressed against the drum with a frictional force stronger than the frictional force of the winding shaft against the roller. Fastening device of stop device. (3) The tightening device for a tire slip prevention device according to claim (1) or (2), wherein a spring device including a spring for setting a minimum tightening force is connected to the middle of the string-like body.
