Claim:
1. An actuator device for a flight control surface which drives a flight control surface of an aircraft, the actuator device comprising: a first actuator that comprises a first output section, and drives the flight control surface; a second actuator that comprises a second output section, and drives the flight control surface instead of the first actuator; and a connection fitting to which each of the first output section and the second output section is connected, wherein the first actuator and the second actuator are connected to the flight control surface via the connection fitting, a first link member, one end of which is rotatably supported on the first actuator and another end of which is rotatably connected to the connection fitting about a rotational axis of the control surface, and a second link member, one end of which is rotatably supported on the second actuator and another end of which is rotatably connected to the connection fitting about the rotational axis of the control surface, wherein in the first actuator, the first output section is rotatably connected to the connection fitting about an axis offset from the rotational axis of the control surface where the first link member and the second link member are rotatably connected, and in the second actuator, the second output section is rotatably connected to the connection fitting about the axis offset from the rotational axis of the control surface, wherein actuation of the first actuator or the second actuator causes the connection fitting to pivot about the rotational axis of the control surface.
