PURPOSE: To surely prevent a vehicle from its burglary by providing a transmitter, carried by a driver, and a receiver, set up in the vehicle, operating the transmitter from the outside of the vehicle and enabling the receiver in a side of the vehicle to generate a stop signal through a radio wave.

CONSTITUTION: A vehicle burglarproof device is provided with a transmitter, carried by a driver, and a receiver set up in a vehicle. When the vehicle is robbed, the driver, by operating the transmitter in the outside of the vehicle, transmits a signal code for stopping the vehicle. This transmitted signal code, in order to prevent misoperation of the device, is a signal code which can be discriminated from the ordinary radio wave. The receiver, when it receives this signal code, generates a stop signal, and being based on this signal, a non- volatile keep relay operates continuously cutting off thereafter a main power source of the vehicle. Accordingly, the vehicle, being placed in a stop condition, can be surely prevented from the burglary.
