PURPOSE:To make it possible to earth at a desired position and to make the process of a conductor cover unnecessary by furnishing an earthing conductor along the longitudinal direction of a wiring duct main body, at the side opposite to the groove aperture of the conductor cover. CONSTITUTION:A wiring duct main body 1 consists of a conductor core 5 and an insulator 6 to cover the surface, and furnishes a groove aperture 31 at the front side, and conductors 3 and 4 at the inner surface in the longitudinal direction. A conductor cover 2 is formed of an elastic substance, and furnishes its main body 16 arranged at the bottom side 15 and a cover piece 17 extended from the main body 16 and covering the surfaces of the conductors 3 and 4, and moreover, furnishes an earthing conductor 18 at the side opposite to the groove aperture 31. A conductive fixing screw is screwed in the wall surface penetrating the earthing conductor 18 and the core 5, the conductor cover 2 is fixed to the wiring duct main body 1 thereby, and the earthing conductor 18 and the core 5 are connected electrically. |
