PURPOSE: Structure for applying an electric current to a steering device is provided to smoothly supply electricity to an air bag and a multifunctional switch even if a part of a steering device is made of plastic. CONSTITUTION: A cathode current of an air bag, a horn or a multifunctional switch is communicated to an upper shaft(108) and a lower shaft(110). The cathode current transferred to a lower bearing(111) via the lower shaft is transferred to a lower tube via a bearing cover(1) between the lower bearing and the lower tube. The cathode current is transferred by an insulator passing unit. The insulating passing unit is a metal plate(3) contacting to the lower tube. Therefore, electricity is smoothly supplied to the air bag, the horn or the multifunctional switch even when electric connection is released.
