題が起こらないようにするものである。Reference numeral 5 denotes a split pin for preventing the pins 3 and 4 from coming off. Reference numeral 8 denotes a tightening coil spring which is inserted into the long bolt 7 and fastened with a nut, and is linked to a support bracket (not shown) so that a compressive force acts on the spring 8 so as to be fixed. Is achieved by tightening. Reference numeral 9 denotes an insulating cover, which covers the pin 3, the connecting metal fitting 2, the clevis pin 4 and the eyebolt 10, which are energized by the pin 3, which is usually a metal member, penetrating through the conductor of the insulating trolley wire 1. This prevents problems such as ground faults.
