PURPOSE: A device for blocking the rain water in the opening of a door is provided to prevent the invasion of the interior of a vehicle with the rain water and to completely prevent a passenger getting on and off the vehicle from wetting by automatically protruding a rain blocking plate toward the upper portion of the door. CONSTITUTION: A rain water blocking switch(4) serially connected between a door switch(2) and a magnetic valve(6) is selectively turned on and off by a driver. While the door switch and the rain water blocking switch are turned on, the magnetic valve supplies the compressed air in an air tank(5) to a cylinder(7) by being operating with the voltage of a battery(1). With response to the air pressure transmitted via the magnetic valve, the cylinder automatically returns a piston with the stoppage of the magnetic valve after protruding the piston by a specific length. A rain water blocking plate(8) is protruded by the driving of the cylinder. If a door(9) is closed, the rain water blocking plate is inserted to the roof of the vehicle.
