PROBLEM TO BE SOLVED: To provide a double torsional damper including a suppression wire having a falling-off preventive mechanism for a weight, preventing the suppression wire from being broken to secure the weight, and easy to find the breaking.SOLUTION: A double torsional damper 100 includes: a suppression wire 10-1; weights 20 fixed to both ends of the suppression wire 10-1; and an electric wire holding clamp 30 fixed to a central portion of the suppression wire 10-1. The suppression wire 10-1 includes core wires 51 having the same outer diameter, and a plurality of outer periphery wires 52. The plurality of outer periphery wires 52 are twisted around the core wire 51. Thin wires 12 are incorporated along grooves formed by twisting the outer periphery wires 52. The incorporated thin wires 12 slacken in a central portion between the weight 20 of the outer periphery wires 52 and the electric wire holding clamp 30. |
