<p>PROBLEM TO BE SOLVED: To solve the problems that, when a tire chain is to be attached, chains of longitudinal tire chains chained in three rows and chains of lateral chains called a cross chain move very unstably because of their individual movement, that in a fastening method of fixing the farthest chains, next fixing the center chains, and last the outermost chains, it takes much labor and time in attaching the tire chain, and that it is difficult to fix the farthest chains each other because they are located at places difficult to reach with hands and at places difficult to be visually recognized.SOLUTION: By fixing both ends of a double chain to a metal attachment auxiliary tool to integrate three rows of longitudinal chains, the tire chain is enabled to be attached on tires under a stable condition. By fixing attachment auxiliary tools at both ends of the tire chain in the stable condition, the tire chain can be attached under the stable condition with a reduced time without individually fixing the farthest chains, the center chains and the outermost chains by fixing the attachment auxiliary tools at both ends each other.</p> |
