A bolt inserted through two bolt insertion holes that are in communication with each other, sandwiching an auxiliary catenary wire fitted with an insulating cover between the two recesses formed in The fastening work can be done by simply tightening the nut on the
In particular, the concave part of the holding part is formed toward the vertical direction of the support arm, and the holding part is hinged so that the joint surface with the holding arm faces the direction perpendicular to the vertical direction of the support arm. Not only can it be opened and closed simply by rotating it, but also when tightening the nut, fastening tools such as spanners can be carried out very easily without being obstructed by the attachment part or the holding part. . In addition, since the insulating cover is divided into two parts and each divided body is hinged at one joint edge, it is necessary to fit the auxiliary catenary wire and sandwich it between the holding part and the holding piece. Can be easily performed with one hand. Further, the support arm vertically provided on the mounting portion does not have a bolt insertion hole or the like formed therein, so that the suspension strength does not decrease and may be damaged by the weight of the auxiliary catenary wire and vibrations when passing the train. There is none.
