Abstract
A vehicle theft detector apparatus includes a key cylinder attached to a door or an opening/closing part, this cylinder having a built-in key switch which sends locked and unlocked signals to an alarm device and a locking device, the lead wires from this lock switch leading to the alarm device and locking device via connectors. When the key cylinder is removed for the purpose of entering the vehicle, the lead wires attached to the cylinder are pulled out from the connector and then the thief enters the vehicle, the alarm is sounded and the thief detected. The above-mentioned detector apparatus is provided with apparatus for taking up the slack in the lead wires, thus ensuring that the connector is immediately disconnected no matter how slightly the cylinder is pulled outwards.
