Abstract

PURPOSE: To prevent the sag of trolley line by a construction wherein the tightening insulator fixed to the trolley line is energized to the predermined direction by the bracket fixed to a separate structure and by the bolt and spring fixed to said bracket.
CONSTITUTION: The hole for insertion of a pin is provided at the insulated trolley line 1. By the insertion of the pin 5 in said hole after inserting the insulated trolley line 1 into the holding groove 3, the insulated trolley line 1 is fixed to the tightening insulator 2. To the separate structure is fixed the bracket 9 to which the one end of the bolt 8 is also fixed. By inserting the bolt 8 in the through hole 4 of the tightening insulator 2 and employing the spring 13 at the other end 8b of bolt 8, the tightening insulator 2 is energized to the direction of the bracket 9 to give tension to the trolley line 1. The fixing insulator 2 is slidably supported by the inwardly-bent portion of the support 14 fixed to the bracket 9 and the bolt 8.
