PROBLEM TO BE SOLVED: To attain suppression of a fluctuation in a hanging position due to lateral wind, the high-speed operation of an electric car, and a stringing structure with easy manufacture, installation and maintenance in a catenary type rigid body electric traction.
SOLUTION: A cut line for clamping a trolley wire is formed at the lower end of a clamping rigid body 1, a protruding edge for expanding the cut line is formed at both sides thereof, and a locking groove 7 for a hanger 12 is formed at both sides thereof. The hanger 12 is suspended from a catenary wire 13, and a clamping rigid body 1 which clamps the trolley wire 11 is suspended from its lower part. The clamping rigid body 1 is formed into a rectangular tubular shape with four corner curved surfaces, so that displacement due to lateral wind is relieved. The locking grooves 7 on both sides have little wind resistance against the lateral wind, so as to contribute to prevent a position fluctuation by wind pressure. By a flat surface at its upper part, torsion at the time of extrusion forming is prevented. The hanger 12 involves engaging parts 16 for engaging with the locking grooves 7 of the clamping rigid body 1. The engaging parts 16 involves engaging pieces and a pressing metal fitting 26, and obtain strong joining quality with easy joining with the clamping rigid body 1. The length of a hanger bar 15 is adjusted easily by a turn buckle 19.
