PROBLEM TO BE SOLVED: To provide a tire ant-skid device which eliminates distortion at the attachment of a tire accompanied by a difference between arrangement forms of a plurality of leg parts which are extended from a tread part, and can improve attachment performance.SOLUTION: In a tire anti-skid device 10 which comprises a tread part 12 in which a grounding part grounded with a traveling face is constituted, and a plurality of leg parts which extend to a width of a tire with the tread part 12 as a base point, the leg parts have a first leg part 18 which extends toward the width direction from an end part of the tread part 12 in a longitudinal direction, and a second leg part 20 which has an inclination from a center side of the tread part 12 to the first leg part 18 side with the tread part 12 as a base point, and extends toward the width direction. The tread part 12 is formed into a circular disc shape by arranging a tip 18a of the first leg part 18 and a tip 20a of the second leg part 20 so as to approximate each other or to be laminated on each other.SELECTED DRAWING: Figure 1
【課題】トレッド部から延設される複数の脚部の配置形態の違いに伴うタイヤ装着時の歪みを解消し、装着性の向上を図ることのできるタイヤ滑り止め装置を提供する。【解決手段】上記課題を解決するためのタイヤ滑り止め装置は、走行面との接地部が構成されるトレッド部12と、トレッド部12を基点としてタイヤの幅方向に延設される複数の脚部と、を備えるタイヤ滑り止め装置10であって、前記脚部は、トレッド部12の長手方向端部から幅方向に延設された第1脚部18と、トレッド部12の中心側から、トレッド部12を基点として第1脚部18側への傾きを持ち、かつ前記幅方向へ向けて延設された第2脚部20とを有し、第1脚部18の先端部18aと第2脚部20の先端部20aとを近接配置または積層配置することで、トレッド部12を円弧状に形状形成する構成としたことを特徴とする。【選択図】図1
