An electric cable tray of an apartment house includes a ceiling fixing plate(1), an angle control part(2) and a lower rotating part. The ceiling fixing plate is fixed to a ceiling through an anchor bolt(12). The angle control part is connected to a lower part of the ceiling fixing plate through an angle adjustment unit(3). The lower rotating part is connected to the lower part of the angle control unit through a rotating unit(5). A cable passes through the lower rotating part. The angle control part includes a upper plate(21), a lower plate(22) and a nut(222). The upper plate and the lower plate are closely fixed to each other by the nut. The lower rotating part consists of an upper body(41) and a lower body(42). A plurality of wire insertion grooves(44) has a semicircular shape and is formed at a lower part of the upper body. The lower body is closely attached to a lower part of the upper body through a connection part(43). The wire insertion grooves having a semicircular shape are formed at an upper part of the lower body. |
