To prevent ''a cable from an electric component mounted on a counter weight'' of construction machinery from being exposed to the outside. An inclined plane 22a is concavely formed on a rear surface plate 22 which constitutes the counter weight 20; the electric component 30, which comprises a backward monitoring camera, communications equipment, a lamp, an alarm, etc., is mounted on the inclined plane 22a; a recessed groove 32, which is formed in a position, near the electric component 30, on a top surface plate 24, is substantially straightly elongated from a part, where the electric component 30 is mounted, of the top surface plate 24 to an end surface plate 23; and a harness 31 is inserted into the recessed groove 32, so as to be guided into a building. |
