Claims

[Claims for Utility Model Registration] 1. A coupling formed by connecting both ends of a center tube between a pair of flanges via a flexible element, in which a conductive coated thin wire is adhered in the circumferential direction to the surface of the flexible element. , and a coupling characterized in that changes in the coated thin wire can be electrically detected. 2. The coupling according to claim 1, wherein the flexible element is formed of a plurality of laminated plates. 3. The coupling according to claim 1, wherein the flexible element is formed of a diaphragm. 4. The coupling according to any one of claims 1 to 3, wherein a change in the energization state due to breakage of the covered thin wire can be detected. 5. The coupling according to claim 3, wherein a change in resistance value due to stretching of the coated thin wire can be detected.
