Tire anti-slip device

A tire anti-slip device comprising:

• an anti-slip body shaped in at least a set of belts and mounted along a tire circumferential direction,
• the anti-slip body having
• a tread portion provided with a ground portion making contact with the ground on its surface,
• a plurality of inner link portions formed to protrude from the tread portion of the anti-slip body to an inner side of a tire in a width direction, and
• a plurality of outer link portions formed to protrude from the tread portion of the anti-slip body to an outer side of the tire in the width direction;
• and
• a tightener for tightening at least a tightening wire to tightly fit the anti-slip body to the tire,
• wherein the tightener of the anti-slip device has a wire guide member provided with a wire guide portion capable of guiding the tightening wire to the width direction of the tire, so that one side face of the wire guide member in the tire circumferential direction is maintained to be close to an end of the anti-slip body, or a portion corresponding to one side position of the wire guide member in the tire circumferential direction is formed integrally with the anti-slip body,
• the wire guide member has
• a tread portion provided with a ground portion making contact with the ground on its surface,
• an inner link portion formed to protrude from the tread portion of the wire guide member to the inner side of the tire in the width direction, and
• an outer link portion formed to protrude from the tread portion of the wire guide member to the outer side of the tire in the width direction,
• the wire guide portion has wire access holes positioned in each of inner and outer link portions,
• a facing end portion of the anti-slip body is arranged to face the other side face of the wire guide member when the anti-slip device is mounted to the tire, and
• both of a distance between the inner link portion of the wire guide member and inner link portion positioned in the facing end portion of the anti-slip body and a distance between the outer link portion of the wire guide member and the outer link portion positioned in the facing end portion of the anti-slip body are reduced in a tightening operation of the tightener.
