PURPOSE:To prevent securely the burglar of a car by inserting a plate so as to switch on and lock the plate, inputting codes so as to make the plate removable and taking out the plate so as to release the lock. CONSTITUTION:When a plate 32 is inserted from the insertion hole 34 of a square frame body 31, the tip part 36a of an engaging lever 36 is engagingly and undrawably locked in an engage hole 33 so that an input switch 18 is held in the 'on' state. In this state, a control circuit makes a car burglar preventing device function. When codes are inputted from an input device and a starting switch is switched on, a solenoid 27 is magnetized so that a plunger 38 is sucked, the engaging lever 36 is rotated to the left against a spring 40, the engagement is released, and the plate 32 becomes drawable. When the plate 32 is taken out, the input switch 18 is switched off and the car burglar preventing device is released from functioning. The car burglar can be thus securely prevented. |
