PROBLEM TO BE SOLVED: To provide a chain connection structure which enables the easy adjustment of an opposing dimension distance between the front end parts of a pair of opposite chain members and enables gradual adjustment as compared with the adjustment of the dimension distance between the front end parts by the selection of an annular chain component at the front end part or a following annular chain component of another chain member, so that it is possible to improve flexibility in the adjustment of the dimension distance between the front end parts of the pair of opposite chain members.SOLUTION: An engagement member 3 is formed so as to be capable of being detachably inserted into an inner hole part 2Kof an annular chain component 2Kat the front end part of another chain member 2 and into an inner hole part 1Kof an annular chain component 1Kat the front end part of one chain member 1. A hook groove part 3b is formed at the front end part of the engagement member. To the annular chain component at the front end part of the one chain member, there is fitted an engagement/detachment ring 4 with which the hook groove part can be detachably engaged. In the middle part of the engagement member, there are formed engagement/detachment groove parts 3c with which a shaft part 2Kof the annular chain component at the front end part of the other chain member can be detachably engaged. The plural engagement/detachment groove parts are formed so as to be sequentially arranged in the serial direction of plural annular chain components K.K...
【課題】対向一対のチェーン部材の先端部間の対向する寸法距離を容易に調節することができ、かつ、他方のチェーン部材の先端部の環状鎖材又は次列の環状鎖材の選択による先端部間の寸法距離の調節に比べて小刻みな調節を行うことができ、対向一対のチェーン部材の先端部間の寸法距離の調節の融通性を向上することができる。【解決手段】係止部材3は他方のチェーン部材2の先端部の環状鎖材2KSの内穴部2KSH及び一方のチェーン部材1の先端部の環状鎖材1KSの内穴部1KSHに挿脱可能に形成され、係止部材の先端部にフック溝部3bが形成され、一方のチェーン部材の先端部の環状鎖材にフック溝部が係脱可能な係脱リング4を嵌装し、係止部材の中程部に他方のチェーン部材の先端部の環状鎖材の軸部2KSPが係脱可能な係脱溝部3cが形成され、係脱溝部は複数個の環状鎖材K・K・・の直列方向に順列状に複数個形成されてなる。【選択図】図2
