PURPOSE:To contrive reduction in the number of parts, in a device in which an insulating trolley wire is supported by an inversed U-shaped hanger fitting via a hanger insulator, by enabling the support and fixture of the insulating trolley wire to the hanger fitting to be carried out only by the hanger insulator. CONSTITUTION:In an inversed U-shaped hanger fitting 1 being supported by a fitting member 4 such as a ceiling frame member, outer lockedly-engaaging projections 16 projectedly provided on the outer surface of the right and left side parts 9, 10 of a hanger insulator 2 are lockedly engaged with respective engaging grooves 18 which are formed by bending the middle parts in the up-and-down direction of the right and left side wall parts 5, 6 in a U-shape. In this case, engaging window parts 7 are formed in the central part, in the front-and-rear direction, of the engaging grooves 18 of the right and left side wall parts 5, 6, while in the right and left parts 9, 10, elastic lockedly engaging parts 8, which are to be engaged with the engaging window parts 7 when they are inserted in the longitudinal direction while sliding on the inner surfaces of the right and left side wall parts 5, 6, are projectedly provided. Further, on the right and left parts 9, 10, lockedly engaging projection parts 11 for abutting on the front-and-rear directional one end surface 21 of the right and left side wall parts 5, 6 are projectedly provided, and also on each of the elastic lockedly engaging parts 8, a gradient part 12 is formed.
