PROBLEM TO BE SOLVED: To provide a side thruster valve for an aircraft, and a side thruster device using the side thruster valve, capable of reducing necessary torque for a servo motor or the like required for opening/closing a nozzle to achieve the compactness and light weight of the device, and improving fuel consumption by separately providing the side thruster valves that are compact and light by enlarging a range of combustion control. SOLUTION: For moving the valve element to change from full opening to full closure, an actuator and a spring are provided, and the spring is set to have natural length at a neutral position of the valve element, so that when the valve element is energized from a full opening or full closure position toward the neutral position, spring force largely contributes to the opening/ closing of the valve element. Necessary torque for the servo motor or the like is reduced, and the device can be compact and light. By providing the valves separately from each other, a plurality of valves are set at symmetric positions around an axial line of the aircraft and full-open-controlled to improve fuel consumption.
