PURPOSE: A burglarproof device for a vehicle is provided to prevent the theft of the vehicle by keeping the operation of a hydraulic brake. CONSTITUTION: The connection state of a key switch(200) is varied according to the key operation of a driver. A first relay(100) and a second relay(110) are connected to an accessory power terminal in the key switch, and are switched on when the key switch is connected to the accessory power terminal. A third relay(120) is connected to an ignition power terminal in the key switch, and is switched on according to the operation of the second relay. A solenoid valve(400,401) shuts off a hydraulic outlet(510,520) in a brake master cylinder(500) when the first and third relays are switched on.
