CONNECTION METAL FITTING FOR BOLT SHANK
PROBLEM TO BE SOLVED: To improve engagement strength of a connection metal fitting engagement part which connects one end of a connection member to a bolt shank, and to allow surface alignment with a connection mating member on the other end side of the connection member without relaxing engagement state even after the portion is engaged with the bolt shank.MEANS FOR SOLVING THE PROBLEM: A connection metal fitting connects one end of a specified connection member to a bolt shank, and a structure of a connection metal fitting engagement part to the bolt shank is a perfect bolt shank hooking engagement structure in which a connection metal fitting engagement holder is combined with an engagement gear holder, for improving engagement strength. A connection member connected to the connection metal fitting engagement part through a connection bolt for pressurizing an engagement gear is not perfectly fixed to a connection part for the connection bolt, but being rotatable relatively at a torque of a specified value or higher.SELECTED DRAWING: Figure 28
【課題】連結部材の一端をボルト軸に連結する連結金具係止部の係止強度を向上させると共に、同部分がボルト軸に係止された後においても、その係止状態を緩めることなく、連結部材他端側の連結相手部材との面合わせを可能とする。【課題解決手段】所定の連結部材の一端をボルト軸に連結する連結金具であって、ボルト軸に対する連結金具係止部の構造を連結金具係止ホルダーと係止ギヤホルダーとの組み合わせによる完全なボルト軸嵌合係止構造として係合強度を向上させるとともに、同連結金具係止部に係止ギヤ押圧用の連結ボルトを介して連結される連結部材と連結ボルトとの連結部を完全な固定ではなく、所定のトルク以上のトルクで相対回転可能とした。【選択図】 図２８
