<p>The present invention relates to a landing device for an air plane in which a linear actuator is not used, but a rotor actuator is used, thereby reducing an operation receiving space; the construction is relatively simple; and the weight is lightened. The landing device includes a landing device body installed to a lower portion of a fuselage; a lower drag support fixed to the landing device body; a motor fixed to the lower drag support to generate rotation power and having a gear unit for transmitting the rotation power; an upper drag support rotatably connected to the lower drag support; and a gear bolt fixed to the upper drag support by a nut and a fixing pin, of which a gear unit is connected to the gear unit of the motor so that the rotation power of the motor acts as reaction force.</p> |
