PURPOSE:To prevent loosening by an elastic force so as to avoid an imperfect electrical connection by achieving fastening using an elastic fastening means. CONSTITUTION:A conductor clamp 8 secured to a cord 11 is inserted into a hole 6 in a plug blade 3a from a secured portion 9a until a flange 10 abuts the side of the blade 3a, and with the center of a conductor inserting portion 9 located at the end of a screw 7, the screw 7 is fastened and the inserting portion 9 is pressed against and sandwiched between the end of the screw 7 and the inner peripheral wall of the hole 6 so that the cord 11 is secured to the blade 3a via the clamp 8. Since the inserting portion 9 is given elasticity, the inserting portion 9 is elastically sandwiched between the end of the screw 7 and the inner surrounding wall of the hole 6. Therefore, the elastic force of the inserting portion 9 keeps the screw 7 from loosening, and even if the clamp 8 is moved as an external force is applied to the cord 11, the clamp 8 is stably secured in position by a predetermined sandwiching force derived from the elastic force of the inserting portion 9. |
