PROBLEM TO BE SOLVED: To surely avoid the short circuit of a battery during parking which may result from degradation or damaging of cables directly connected to the plus terminal of the battery, such as those leading from the plus terminal of the battery to a key switch. SOLUTION: A pair of conductor plates 13, 14, which are joined together by the transmission of power to a solenoid 12 and thus made to conduct electricity and which are separated and insulated from each other by cutting off the power, is provided, the conductor plate 14 being connected to the minus terminal of a battery 1, the conductor plate 13 being grounded to a vehicular body 4. A current is carried to the solenoid 12 by the switching-on of a key switch 2 connected to the plus terminal of the battery 1 via cables 9, 11, and the current-carrying is cut off by the switching-off of the key switch 2. |
