PROBLEM TO BE SOLVED: To provide a tire chain configured to reduce loss of elasticity restoring force of an elastic member that expands an outer side chain part in a circumference direction.SOLUTION: The tire chain has a tension generating mechanism constituted of: a lock guide 111 which has a separated part 61a to be circumferentially separated formed at an outer side chain part 61 and is attached to one side of the outer side chain part 61 through the separated part 61a; a hook (a locked member ) 121 attached to the other side of the outer side chain; a lead chain 131, inserted through the inside of the lock guide 111, one side of which can be engaged with the hook (the locked member) 121; an adjustment spring 141, one end part of which is attached to the other side of the lead chain 131 and the other end part of which can be engaged with the other side of the outer side chain part 61 through the separated part 61a; and an additional tightening spring 151, one end part of which is attached to the hook (the locked member) 121 and the other end part of which is attached to the one side of the outer side chain part 61 through the separated part 61a.SELECTED DRAWING: Figure 1
【課題】外側サイドチェーン部を周方向に張る弾性部材の弾性復元力のロスが少なくなるタイヤチェーンを提供することを課題とする。【解決手段】外側サイドチェーン部61に、周方向に分離する分離部61aを形成し、分離部61aを介して外側サイドチェーン部61の一方の側に取り付けられたロックガイド111と、他方の側に取り付けられたフック(被係止部材)121と、ロックガイド111の内部を挿通し、一方の側がフック(被係止部材)121に係脱可能なリードチェーン131と、リードチェーン131の他方の側に一方の端部が取り付けられ、他方の端部が分離部61aを介して外側サイドチェーン部61の他方の側に係脱可能な調整スプリング141と、一方の端部がフック(被係止部材)121に、他方の端部が外側サイドチェーン部61の分離部61aを介して一方の側に取り付けられた増し締めスプリング151と、からなる張力発生機構を有する。【選択図】図1
