PROBLEM TO BE SOLVED: To enhance the mechanical rigidity (servo rigidity) of an actuator while minimizing the dimensions of an actuator mounting part to compactly constitute the whole device. SOLUTION: The actuator 1 comprises a hydraulic cylinder 2 and a trunnion type universal joint 3. The trunnion type universal joint 3 is composed of a mounting shaft 31, a clamping member 32 disposed on the mounting shaft 31 rotatably around the axis of the mounting shaft 31 as the rotation center and projected in the axis direction of the mounting shaft 31, and a holding member 33 turnably journaled into the clamping member 32 in an orthogonal direction to the rotating direction of the clamping member 32 to hold the hydraulic cylinder 2.
