To provide wire attachment hardware which cuts down on the cost of a product by using a normal thread terminal, and which prevents a cover attached to a connection to a support from being removed by a mischievous act.

A washer 14 is fitted to a rod screw 12 which is attached to the support 2, and a joint member 15 is screwed. Then an arrangement nut 16 is screwed to a screw part 21 on one end side of the thread terminal 17. One end of the wire 7 is fixed to the wire-fixation part on the other end side of the thread terminal 17, and the cover 18 is inserted beforehand. The screw part 21 of the thread terminal 17 is screwed to the joint member 15. After the part 21 is thrusted, and the wire 7 is extended, pressure welding of the arrangement nut 16 is performed to the joint member 15, and the position of the thread terminal 17 with respect to the joint member 15 is fixed. Then the cover 18 is moved to the support 2 side, and an engagement groove on the inner side of a cover opening is engaged with a stopper ring 20 provided to the washer. Thus, the cover 18 can be rotated, but cannot be moved in the axial direction.
