To solve such a problem that there is possibility that vibration fatigue and loosening of a screw body due to vibration occur when an overhead power line for an electric car track oscillates and so on in an overhead power line metal fitting for an electric car tract that pinches the overhead power line for an electric car track by fastening the screw body.SOLUTION: An overhead power line metal fitting comprises: a first pinching body 2 having a first pinching part 2a and a storage part 5; and a second pinching body 3 having a second pinching part 3a, a fit-in part 6 which has an insertion hole 3c in which a male screw part 30b can be inserted and which can be accommodated in the storage part 5, and a second female screw part 11 in which a first spiral strip 12 that is coaxial with the insertion hole 3c and can engage with a first spiral groove 31 is formed. By spirally rotating the male screw part 30b and the first female screw part 11 relatively, the fit-in part 6 can be advanced and retreated in the storage part 5.SELECTED DRAWING: Figure 6
【課題】ねじ体を締め付けることで電車線路用架線を挟持する電車線路用架線金具において、電車線路用架線が振動等した場合には、振動疲労や、振動によるねじ体の緩みが生じる虞がある。【解決手段】第一挟持部2aと収容部5とを有する第一挟持体2と、第二挟持部3aと、内部に雄ねじ部30bを挿入し得る挿入孔3cを有し、収容部5に収容し得る挿嵌部6と、挿入孔3cと同軸で第一螺旋溝31を螺合し得る第一螺旋条12が形成されて成る第一雌ねじ部11と、を有する第二挟持体3とを備え、雄ねじ部30bと第一雌ねじ部11とを相対螺転させることで、挿嵌部6を収容部5内において進退させ得るように構成する。【選択図】図6
