底部32が碍子に支持される。(Prior Art and its Problems) The conventional rigid electric wire has a steel base 30 having low conductivity which is not involved in energization as shown in FIG. 3, and a flange 35 of the base 30 is fixed to an insulator. The main trolley member 10 made of copper (or aluminum) having high conductivity is disposed in the trolley main body 10, and the trolley main member 10 is sandwiched between a pair of ear fittings 33. Ear fittings 33 are bolts 37 and nuts penetrating both side walls 31 of the gantry 30
It is fastened and fixed to the gantry 30 by 38. Since the trolley main member 10 is in direct contact with the current collecting shoe, hard copper is used in consideration of wear resistance. The gantry 30 has its flange 35 and bottom 32 supported by insulators.

を高めるために大型化する必要がある。In the rigid electric wire using the steel base 30 as described above, the cross-sectional area of the trolley main member 10 is considered to be the energized area,
Therefore, when increasing the current capacity, the sectional area of the trolley main member 10 is increased in accordance with the capacity. The gantry 30 supporting the trolley main member 10 having an increased cross-sectional area also needs to be enlarged in order to increase its rigidity and strength.
ところが大きな断面積の硬銅製のトロリ主材10を製造
することは、コスト面及び製造技術面で困難がある。However, it is difficult to manufacture the hard copper trolley main member 10 having a large cross-sectional area in terms of cost and manufacturing technology.

も低下する。The gantry 30 is hollowed out as shown in FIG. 3 to reduce the weight.
When tightening the ear fitting 33 to the wall surface 31, the side wall 31 bends inwardly if it is excessively tightened, and accordingly the tip claw 33a of the ear fitting 33 opens, and the trolley main member 10 rattles. . Of course, if the side wall 31 is largely bent, the durability of the gantry 30 is also reduced.

することができる。Moreover, in the present invention, when the bolt and the cylinder nut are tightened as described above, the side walls 3 and 4 of the gantry 1 are slightly bent, and the tip 20d of the cylinder nut 20 abuts on the inner surface of the second side wall 4. This serves as a stopper and prevents further excessive tightening of the bolt and nut. The hollow frame made of copper, aluminum, or the like of the present invention, which is softer than the steel frame, bends and deforms due to excessive attachment of bolts and nuts. This can be effectively prevented by the stopper function described above.
