Zusammenfassung:PURPOSE: An apparatus is provided to prevent discomfort of passenger by easily discharging room air to outside upon closure of vehicle door and thus preventing room pressure rise. CONSTITUTION: An apparatus comprises a magnet(1) mounted to a vehicle door; a coil(2) mounted to a vehicle body; a transistor driving unit(3) for driving each transistor(T1,T2,T3) by separately outputting the induction current generated from the coil in accordance with the intensity of the current; transistors serving as switches for power of a battery; resistors(R1,R2,R3) connected to transistors, respectively, which permit the power being supplied to a motor to have different intensity; and the motor for receiving power from the battery through resistors, and controlling the degree of opening/closing of a vent door of an outdoor air inlet port.
