PROBLEM TO BE SOLVED: To provide a blind rotation mechanism capable of securing safety even when operation force equal to or greater than prescribed force has applied in the axial direction of an operation chain, and capable of easily restoring a connector to its original state.SOLUTION: A connector 170 for connecting both ends of an operation chain 160 to make the chain be in a loop shape includes: a first insertion part 171 which is provided at one end of the operation chain 160, and into which a ball part 161 is to be inserted; and a second insertion part 172 which is provided on the side opposite to the first insertion part 171, and into which a ball part 161 provided at the other end of the operation chain 160 is to be inserted. At the second insertion part 172 is formed an easily deformable part 172b, which is deformed to enable the ball part 161 to separate from the second insertion part 172 when operation force equal to or greater than prescribed force has applied in the axial direction of the operation chain 160. Thereby, even when operation force equal to or greater than the prescribed force has applied in the axial direction of the operation chain 160, safety is secured and the connector 170 can be easily restored to its original state.SELECTED DRAWING: Figure 6
【課題】操作チェーンの軸方向に一定以上の操作力が作用しても安全性を担保でき、コネクタを容易に元の状態に復帰させることの可能な、ブラインドの回転機構を提供する。【解決手段】操作チェーン１６０の両端部を接続してループ状とするためのコネクタ１７０は、操作チェーン１６０の一端部に設けられるボール部１６１が挿入される第１挿入部１７１と、第１挿入部１７１の反対側に設けられ、操作チェーン１６０の他端部に設けられるボール部１６１が挿入される第２挿入部１７２と、を有し、第２挿入部１７２には、操作チェーン１６０の軸方向に一定以上の操作力が作用した場合に変形してボール部１６１が第２挿入部１７２から離脱可能となる易変形部１７２ｂが形成されている。これにより、操作チェーン１６０の軸方向に一定以上の操作力が作用しても安全性を担保でき、コネクタ１７０を容易に元の状態に復帰できる。【選択図】図６
