PROBLEM TO BE SOLVED: To intercept certainly on-vehicle electrical equipment from a power source, thereafter adopt quick protective measures in vehicle collision. SOLUTION: A collision detector 66 detecting vehicle collision, and a main fusible like FE1 disconnecting an electric conductor for fuse 20 to intercept between a battery BT and on-vehicle electrical equipment during detecting vehicle collision, are provided. A carriage return circuit 60 is parallelly provided to the electric conductor for fuse 20, and another electric conductor for fuse 61 and an open circuit part 64 are arranged in series to the carriage return circuit 60. After disconnecting the electric conductor for fuse 20, a driver or the like mounts a connecting member on the open circuit part 64, thereby, contacts of the open circuit part 64 are connected to each other, then electric power is supplied from the battery BT to the on-vehicle electrical equipment through the carriage return circuit 60. |
