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 |
