1. An aircraft control surface drive mechanism that is provided as a link mechanism comprising a hydraulically operated actuator and a reaction link connected to the actuator, and that drives a control surface of an aircraft, wherein the actuator includes a plurality of cylinder units each including a cylinder and a rod, and is pivotably attached, at a first end thereof, to the control surface or a control surface-side member attached to the control surface, andthe reaction link is pivotably attached, at a first end thereof, to a fulcrum shaft rotatably supporting the control surface, and is pivotably attached, at a second end thereof, to a second end of the actuator between the plurality of cylinder units. 2. The aircraft control surface drive mechanism according to claim 1, wherein the plurality of cylinders of the actuator are formed integrally or joined integrally. 3. The aircraft control surface drive mechanism according to claim 1, wherein the actuator further includes a rod end portion that joins the respective rods of the plurality of cylinder units and that is pivotably connected to the control surface or the control surface-side member. 4. The aircraft control surface drive mechanism according to claim 1, wherein the reaction link is provided with a widened portion that is formed so as to spread in a width direction, which is a direction perpendicular to a longitudinal direction of the reaction link, toward an end portion thereof at the first end pivotably attached to the fulcrum shaft. 5. The aircraft control surface drive mechanism according to claim 1, wherein the reaction link is pivotably attached, in two locations at the first end, to the fulcrum shaft, and is pivotably attached, in one location at the second end, to the second end of the actuator. 6. The aircraft control surface drive mechanism according to claim 5, wherein the actuator is pivotably connected, in two locations at the first end, to the control surface or the control surface-side member.
